Description

  The present invention relates to a data processing technique, and more particularly to a document processing apparatus that processes data consisting of a plurality of documents.

  In recent years, with the spread of computers and the advancement of network technology, the exchange of electronic information via the network has become popular. As a result, many of the business processes that have been conventionally performed on a paper basis are being replaced by network-based processes.

  Even in companies, so-called knowledge management, which utilizes personal knowledge and information throughout the organization, has become an important management technique. Many companies have in-house database systems that store information from employees in electronic files. On the other hand, employees also access files stored in this in-house database via the network. As a result, the business efficiency of the entire organization is improved.

  Many of the files stored in this in-house database are created in a language called HTML (Hyper Text Markup Language). In recent years, there are many examples in which these files are created using a language called XML (eXtensible Markup Language).

  HTML is a language for describing web pages. In other words, HTML is a kind of markup language that defines how to display a document file. On the other hand, XML is a language having a function for defining a data structure of data included in a document file, rather than a language for directly describing a web page like HTML. . The document file created by XML is displayed as a web page by giving display layout information separately. That is, in an XML document, the data structure and its display layout can be handled separately. A language for generating a markup language, such as XML, is also called a meta language.

XML is attracting attention as a format suitable for sharing data with others via a network or the like, and an application for creating, displaying, and editing an XML document has been developed (for example, see Patent Document 1). ). The XML document is created based on a vocabulary (tag set) defined by a document type definition or the like.
JP 2001-290804 A

  In many departments in a company, as described above, an electronic document file is created and updated using an application for editing a document such as XML. Under such circumstances, the present inventor has recognized the following problems. That is, when a document file is created from a plurality of applications, it is a problem that the corresponding application must be started up every time the document file is created or edited. For example, there may be a case where a document is created by each of an application having a word processor function, an application having a spreadsheet function, and an application having a drawing function, and is integrated into one file for editing.

  The present invention has been made in view of such circumstances, and an object thereof is to provide a document processing apparatus and a document processing method capable of processing a document created by a plurality of tag sets.

  In order to solve the above problems, a document processing apparatus according to an aspect of the present invention is a document processing apparatus that processes a document composed of partial documents each described by a plurality of tag sets having a specific hierarchical structure. A plurality of processing systems for processing each document and a document display area for displaying a partial document are assigned to each of the partial documents, the corresponding partial document is displayed in the document display area, and An editing unit that accepts editing.

  Here, “a plurality of tag sets having a specific hierarchical structure” includes that each tag set is hierarchized so as to have other tag sets therein. The “partial document described by each tag set” includes a document described by a specific markup language or vocabulary. “Multiple processing systems for processing each partial document” includes software for decoding a markup language or vocabulary applied to a tag set describing a partial document and displaying it on a screen. It includes processing systems such as HTML (Hyper Text Markup Language) and SVG (Scalable Vector Graphics).

  It should be noted that any combination of the above components, the components and expressions of the present invention, or a part of them may be mutually exchanged between methods, apparatuses, systems, computer programs, recording media storing computer programs, data structures, Those substituted with are also effective as an embodiment of the present invention.

  According to the present invention, there is an effect in improving user convenience in handling data included in a structured document file described by a plurality of tag sets.

  First, an outline of a document processing apparatus according to an embodiment of the present invention will be described. The document processing apparatus includes an editing unit, a plurality of processing systems, a display control unit, and a hierarchy analysis unit. The user creates various documents using a plurality of markup languages or a plurality of vocabularies. These individual markup languages are called tag sets. A user can edit a sentence by describing a plurality of tag sets so as to have a hierarchical structure, and each of the plurality of tag sets is processed by a corresponding processing system. The plurality of processed tag sets are integrated by the editing unit and displayed as one document in the document display area on the screen. Each document displayed on the screen has its boundary displayed by the display control unit. When the user edits the document displayed on the screen, the boundary of the document corresponding to the designated portion (hereinafter referred to as “partial document”) is displayed in a manner that can be distinguished from other boundaries.

  The hierarchical analysis unit analyzes the hierarchical structure of the processing system included in the document, and the display control unit displays the name and hierarchical relationship in the hierarchical display area. When the user designates the displayed hierarchy, the boundary of the corresponding document is displayed in a manner that can be distinguished from other boundaries. Similarly, by designating a document displayed in the document display area, the corresponding hierarchy is displayed in a manner that can be distinguished from other hierarchies. The name of the file included in the document is displayed in the file name display area. As described above, when the user designates the name displayed in the file name display area, the corresponding document or the corresponding hierarchy is displayed in a form that can be distinguished from others.

  Each processing system has a plurality of document editing functions. When the user designates a document displayed in the document display area, the document editing function of the processing system that processes the document is displayed in the menu display area. When the user designates a hierarchy displayed in the hierarchy display area, the name of the document editing function of the processing system related to that hierarchy is displayed in the menu display area. When the user designates a hierarchy displayed in the file name display area, the name of the processing document editing function related to the file name is displayed in the menu display area. In either case, the name of the document editing function of the processing system related to the hierarchy higher than the processing system related to the designation may be displayed in the menu display area.

  The configuration and operation of the document processing apparatus in this embodiment will be described below.

  FIG. 1 is a diagram showing a configuration of a document processing apparatus 20 according to an embodiment of the present invention. The document processing apparatus 20 processes a structured document in which data in the document is classified into a plurality of components having a hierarchical structure. In this embodiment, an example of processing an XML document as an example of a structured document will be described. . The document processing apparatus 20 is represented by a main control unit 22, an editing unit 24, a display control unit 110, a document object model unit 30 (Document Object Model Unit, hereinafter abbreviated as “DOM unit 30”), and a processing system. Cascading Style Sheet Unit 40 (hereinafter abbreviated as “CSS unit 40”), HTML unit 50, SVG unit 60, and vocabulary connection unit 80 (Vocabulary Connection Unit; hereinafter referred to as “VC unit 80”). For short). In terms of hardware components, these configurations are realized by a CPU of a computer, a memory, a program loaded in the memory, and the like, but here, functional blocks realized by their cooperation are illustrated. Accordingly, those skilled in the art will understand that these functional blocks can be realized in various forms by hardware only, software only, or a combination thereof.

  The main control unit 22 provides a framework for loading plug-ins and executing commands. The editing unit 24 provides a framework for editing an XML document. The document display and editing functions in the document processing apparatus 20 are realized by plug-ins, and necessary plug-ins are loaded by the main control unit 22 or the editing unit 24 according to the type of document. The main control unit 22 or the editing unit 24 refers to the name space of the XML document to be processed, determines which vocabulary the XML document is described in, and a display or editing plug corresponding to the vocabulary Load the in to display and edit. For example, the document processing apparatus 20 has a display system and an editing system as plug-ins for each vocabulary (tag set) such as an HTML unit 50 that displays and edits HTML documents and an SVG unit 60 that displays and edits SVG documents. The HTML unit 50 is loaded when editing an HTML document, and the SVG unit 60 is loaded when editing an SVG document. As will be described later, when a compound document including both HTML and SVG components is to be processed, both the HTML unit 50 and the SVG unit 60 are loaded. Further, when loading the above-described plug-in, the function related to the plug-in may be displayed in the menu display area.

  According to such a configuration, the user can select and install only necessary functions, and can add or delete functions as appropriate later, so that the storage area of a recording medium such as a hard disk for storing the program is effective. In addition, it is possible to prevent the memory from being wasted when executing the program. In addition, it has excellent function extensibility, and as a development entity, it is possible to handle new vocabularies in the form of plug-ins, making development easier, and as a user, adding plug-ins makes it easy and low-cost. Functions can be added.

  The editing unit 24 receives an editing instruction event from the user via the user interface, notifies the event to an appropriate plug-in, and performs processing such as event re-execution (redo) or execution cancellation (undo). Control. Further, when a document to be edited by the user is read, a partial document included in the document is analyzed. Specifically, a processing system for processing the partial document is selected. Moreover, the hierarchical structure of the tag set concerning the partial document is analyzed. A document display area for displaying a partial document is assigned to each partial document. The corresponding partial document is displayed in the assigned document display area, and the editing of the partial document by the user is accepted. Details will be described later.

  The display control unit 110 controls display on the screen based on an instruction from the user received via the editing unit 24. The display control unit 110 displays the boundary of the document display area. Details will be described later.

  The DOM unit 30 includes a DOM providing unit 32, a DOM generation unit 34, and an output unit 36, and is a document object model (Document Object Model; hereinafter referred to as providing an access method when handling an XML document as data). A function compliant with “DOM”) is realized. The DOM providing unit 32 is an implementation of DOM that satisfies the interface defined in the editing unit 24. The DOM generation unit 34 generates a DOM tree from the XML document. As will be described later, when the XML document to be processed is mapped to another vocabulary by the VC unit 80, the source tree corresponding to the mapping source XML document and the destination tree corresponding to the mapping destination XML document Is generated. The output unit 36 outputs the DOM tree as an XML document at the end of editing, for example.

  The CSS unit 40 includes a CSS analysis unit 42, a CSS providing unit 44, and a rendering unit 46, and provides a display function compliant with CSS. CSS is a language for designating an HTML display style, and corresponds to a child processing system associated with the HTML unit 50. The CSS can specify fonts and colors. The CSS analysis unit 42 has a parser function of analyzing the CSS syntax. The CSS providing unit 44 is an implementation of a CSS object, and performs a CSS cascade process on the DOM tree. The rendering unit 46 is a CSS rendering engine, and is used to display and render a document described in a vocabulary such as HTML laid out using the CSS.

  The HTML unit 50 displays or edits a document described in HTML. The SVG unit 60 displays or edits a document described in SVG. These display / editing systems are realized in the form of plug-ins, and are respectively an HTML display unit (Canvas) 56 for displaying a document, an SVG display unit 66, and an HTML control unit (Editlet) for transmitting and receiving events including editing instructions. ) 52, an SVG control unit 62, an HTML editing unit (Zone) 54 that receives an editing command and edits the DOM, and an SVG editing unit 64. When the HTML control unit 52 or the SVG control unit 62 receives a DOM tree editing command from the outside, the HTML editing unit 54 or the SVG editing unit 64 changes the DOM tree, and the HTML display unit 56 or the SVG display unit 66 updates the display. To do. These have a configuration similar to a framework called MVC (Model-View-Controller), and in general, the HTML display unit 56 and the SVG display unit 66 are set to “View”, and the HTML control unit 52 and the SVG control unit 62. Corresponds to “Controller”, and the HTML editing unit 54, the SVG editing unit 64, and the DOM entity correspond to “Model”, respectively. The document processing apparatus 20 according to the present embodiment enables not only editing of an XML document in a tree display format but also editing according to each vocabulary. For example, the HTML unit 50 provides a user interface for editing an HTML document in a manner similar to a word processor, and the SVG unit 60 provides a user interface for editing an SVG document in a manner similar to an image drawing tool. To do.

  The VC unit 80 includes a mapping unit 82, a definition file acquisition unit 84, and a definition file generation unit 86. By mapping a document described in a certain vocabulary to another vocabulary, a display corresponding to the mapping destination vocabulary Provides a framework for displaying or editing a document with an editing plug-in. In this embodiment, this function is called a vocabulary connection (VC). The definition file acquisition unit 84 acquires a script file describing a mapping definition. This definition file describes the correspondence (connection) between nodes for each node. At this time, whether or not the element value and attribute value of each node can be edited may be designated. Also, an arithmetic expression using the element value or attribute value of the node may be described. These functions will be described in detail later. The mapping unit 82 refers to the script file acquired by the definition file acquisition unit 84, causes the DOM generation unit 34 to generate a destination tree, and manages the correspondence between the source tree and the destination tree. The definition file generator 86 provides a graphical user interface for the user to generate a definition file.

  When the VC unit 80 monitors the connection between the source tree and the destination tree and receives an editing instruction from the user via the user interface provided by the plug-in responsible for display, the VC unit 80 first selects the corresponding node of the source tree. change. When the DOM unit 30 issues a mutation event to the effect that the source tree has been changed, the VC unit 80 receives the mutation event, and the node changed to synchronize the destination tree with the change of the source tree. Change the destination tree node corresponding to. A plug-in for displaying / editing the destination tree, for example, the HTML unit 50, receives a mutation event indicating that the destination tree has been changed, and updates the display with reference to the changed destination tree. With such a configuration, even a document described in a local vocabulary used by a small number of users can be displayed by converting it to another major vocabulary, and an editing environment is provided. Is done.

  An operation for displaying or editing a document by the document processing apparatus 20 will be described. When the document processing apparatus 20 reads a document to be processed, the DOM generation unit 34 generates a DOM tree from the XML document. Further, the main control unit 22 or the editing unit 24 determines the vocabulary describing the document with reference to the name space. If a plug-in corresponding to the vocabulary is installed in the document processing apparatus 20, the plug-in is loaded to display / edit the document. If the plug-in is not installed, check whether the mapping definition file exists. When the definition file exists, the definition file acquisition unit 84 acquires the definition file, generates a destination tree according to the definition, and displays / edits the document by the plug-in corresponding to the mapping destination vocabulary. In the case of a compound document including a plurality of vocabularies, corresponding portions of the document are displayed / edited by plug-ins corresponding to the respective vocabularies, as will be described later. If the definition file does not exist, the document source or tree structure is displayed, and editing is performed on the display screen.

  FIG. 2 is a diagram illustrating an example of an XML document to be processed by the document processing apparatus 20 in FIG. This XML document is used to manage student performance data. The component “score” which is the top node of the XML document has a plurality of component “students” provided for each student under the subordinate. The component “student” has an attribute value “name” and child elements “national language”, “mathematics”, “science”, and “society”. The attribute value “name” stores the name of the student. The constituent elements “National language”, “Mathematics”, “Science”, and “Society” store the results of national language, mathematics, science, and society, respectively. For example, a student whose name is “A” has a national language grade of “90”, a mathematics grade of “50”, a science grade of “75”, and a social grade of “60”. Hereinafter, the vocabulary (tag set) used in this document is referred to as a “results management vocabulary”.

  Since the document processing apparatus 20 of the present embodiment does not have a plug-in that supports display / editing of the grade management vocabulary, the VC function described above is used to display this document by a method other than source display and tree display. Used. That is, it is necessary to prepare a definition file for mapping the grade management vocabulary to another vocabulary provided with a plug-in, such as HTML or SVG. A user interface for the user himself to create a definition file will be described later, and here, the description will proceed assuming that a definition file has already been prepared.

  FIG. 3 is a diagram showing an example of mapping the XML document shown in FIG. 2 to a table described in HTML. In the example of FIG. 3, the “student” node of the grade management vocabulary is associated with a row (“TR” node) of a table (“TABLE” node) in HTML, and an attribute value “name” is assigned to the first column of each row. The second column contains the element values of the “National Language” node, the third column the element values of the “Mathematics” node, the fourth column the element values of the “Science” node, and the fifth column “Society”. The node element values are associated with each other. Thereby, the XML document shown in FIG. 2 can be displayed in an HTML table format. These attribute values and element values are specified to be editable, and the user can edit these values using the editing function of the HTML unit 50 on the HTML display screen. In the sixth column, an arithmetic expression for calculating a weighted average of national language, mathematics, science and social results is designated, and the average score of the students' results is displayed. In this way, by making it possible to specify an arithmetic expression in the definition file, more flexible display is possible and user convenience during editing can be improved. Note that the sixth column specifies that editing is not possible, and only the average score cannot be edited individually. As described above, by making it possible to specify whether or not editing can be performed in the mapping definition, it is possible to prevent an erroneous operation by the user.

  4A and 4B show examples of definition files for mapping the XML document shown in FIG. 2 to the table shown in FIG. This definition file is described in a script language defined for the definition file. In the definition file, command definitions and display templates are described. In the example of FIGS. 4A and 4B, “add student” and “delete student” are defined as commands, respectively, an operation of inserting a node “student” into the source tree, An operation for deleting the node “student” is associated. As a template, it is described that headings such as “name” and “national language” are displayed on the first line of the table, and the contents of the node “student” are displayed on and after the second line. In the template that displays the contents of the node "Student", the term described as "text-of" means "editable" and the term described as "value-of" is "not editable" It means that. In the sixth column of the row displaying the contents of the node “Student”, the formula “(src: Japanese + src: Mathematics + src: Science + src: Society) div 4” is described. , Which means that the average of the student's grades is displayed.

  FIG. 5 shows an example of a screen in which the XML document described in the grade management vocabulary shown in FIG. 2 is mapped and displayed in HTML according to the correspondence shown in FIG. In each row of Table 90, from the left, the name of each student, national language grade, mathematics grade, science grade, social grade, and average score are displayed. The user can edit the XML document on this screen. For example, when the value of the second row and third column is changed to “70”, the element value of the source tree corresponding to this node, that is, the math grade of the student “B” is changed to “70”. At this time, the VC unit 80 changes the corresponding part of the destination tree so that the destination tree follows the source tree, and the HTML unit 50 updates the display based on the changed destination tree. Therefore, also in the table on the screen, the mathematics score of the student “B” is changed to “70”, and the average score is changed to “55”.

  On the screen shown in FIG. 5, commands “add student” and “delete student” are displayed in the menu as defined in the definition file shown in FIGS. When the user selects these commands, the node “student” is added or deleted in the source tree. As described above, the document processing apparatus 20 according to the present embodiment can not only edit the element value of the component at the end of the hierarchical structure but also edit the hierarchical structure. Such a tree structure editing function may be provided to the user in the form of a command. Further, for example, a command for adding or deleting a table row may be associated with an operation for adding or deleting the node “student”. In addition, a command for embedding another vocabulary may be provided to the user. Using this table as an input template, new student grade data can be added in the form of hole filling. As described above, the VC function makes it possible to edit a document described in the grade management vocabulary while using the display / editing function of the HTML unit 50.

  FIG. 6 is a diagram illustrating an example of a graphical user interface presented to the user by the definition file generation unit 86 of FIG. 1 in order for the user to generate a definition file. In the first area 91 on the left side of the screen, a mapping source XML document is displayed in a tree form. The second area 92 on the right side of the screen shows the screen layout of the XML document that is the mapping destination. This screen layout can be edited by the HTML unit 50, and the user creates a screen layout for displaying a document in the second area 92 on the right side of the screen. Then, the node of the mapping source XML document displayed in the first area 91 on the left side of the screen is dragged into the HTML screen layout displayed in the second area 92 on the right side of the screen with a pointing device such as a mouse. By performing the drop operation, the connection between the mapping source node and the mapping destination node is specified. For example, when “mathematics” which is a child element of the element “student” is dropped on the first row and the third column of the table 90 of the HTML screen, the connection is made between the “math” node and the “TD” node in the third column. Is stretched. Each node can be designated for editing. An arithmetic expression can also be embedded in the display screen. When the editing of the screen is finished, the definition file generator 86 generates a definition file describing the screen layout and the connection between the nodes.

  Viewers and editors corresponding to major vocabularies such as XHTML, MathML, and SVG have already been developed, but viewers and editors corresponding to documents described in original vocabulary such as the document shown in FIG. 2 are developed. Is not realistic. However, if a definition file for mapping to other vocabularies is created as described above, the document described in the original vocabulary can be displayed using the VC function without developing a viewer or editor. Can be edited.

  FIG. 7 is a diagram showing another example of the screen layout generated by the definition file generation unit 86 of FIG. In the example of FIG. 7, a table 90 and a pie chart 93 are created on a screen for displaying an XML document described in the grade management vocabulary. This pie chart 93 is described in SVG. As will be described later, the document processing apparatus 20 according to this embodiment can process a compound document including a plurality of vocabularies in one XML document. Therefore, as shown in this example, a table 90 described in HTML and , A pie chart 93 written in SVG can be displayed on one screen.

  FIG. 8 is a diagram showing an example of an XML document editing screen by the document processing apparatus 20 of FIG. In the example of FIG. 8, one screen is divided into a plurality of parts, and XML documents to be processed are displayed in a plurality of different display formats in the respective areas. The source of the document is displayed in the third area 94, the tree structure of the document is displayed in the fourth area 95, and described in the HTML shown in FIG. 5 in the fifth area 96. A table is displayed. Documents can be edited on any of these screens. When the user edits on any of these screens, the source tree is changed, and the plug-in responsible for displaying each screen is changed to the source tree. Update the screen to reflect your changes. Specifically, as a listener for a mutation event that notifies a change in the source tree, a display unit of a plug-in responsible for displaying each editing screen is registered, and the source is generated by any plug-in or VC unit 80. When the tree is changed, all display units displaying the edit screen receive the issued mutation event and update the screen. At this time, if the plug-in is displaying by the VC function, the VC unit 80 changes the destination tree following the change of the source tree, and then refers to the changed destination tree to change the plug-in. The display unit updates the screen.

  For example, when the source display and tree display are realized by a dedicated plug-in, the source display plug-in and the tree display plug-in do not use the destination tree, but directly display the source tree. Do. In this case, when editing is performed on any of the screens, the source display plug-in and the tree display plug-in update the screen with reference to the changed source tree and take charge of the screen of the fifth area 96. The HTML unit 50 updates the screen by referring to the changed destination tree following the change of the source tree.

  The source display and tree display can also be realized using the VC function. In other words, the source and tree structure may be laid out in HTML, the XML document may be mapped to the HTML, and displayed by the HTML unit 50. In this case, three destination trees of a source format, a tree format, and a table format are generated. When editing is performed on any of the screens, the VC unit 80 changes the source tree, then changes each of the three destination trees in the source format, tree format, and table format, and the HTML unit 50 sets the destination tree. 3 screens are updated with reference to the nation tree.

  As described above, the convenience of the user can be improved by displaying the document in a plurality of display formats on one screen. For example, the user can display and edit the document in a visually easy-to-understand format using the table 90 or the like while grasping the hierarchical structure of the document by the source display or the tree display. In the above example, one screen is divided and screens in a plurality of display formats are simultaneously displayed. However, a screen in one display format may be displayed on one screen, and the display format may be switched according to a user instruction. . In this case, the main control unit 22 receives a display format switching request from the user, and instructs each plug-in to switch the display.

  FIG. 9 is a diagram illustrating another example of an XML document edited by the document processing apparatus 20. In the XML document shown in FIG. 9, the XHTML document is embedded in the “foreignObject” tag of the SVG document, and further, the mathematical formula described in MathML is included in the XHTML document. In such a case, the editing unit 24 refers to the name space and distributes the drawing work to an appropriate display system. In the example of FIG. 9, the editing unit 24 first causes the SVG unit 60 to draw a quadrangle, and then causes the HTML unit 50 to draw an XHTML document. Further, a mathematical expression is drawn in a MathML unit (not shown). Thus, a compound document including a plurality of vocabularies is appropriately displayed. The display result is shown in FIG.

  During document editing, the displayed menu may be switched according to the position of the cursor (carriage). That is, when the cursor exists in the area where the SVG document is displayed, the menu defined by the menu provided by the SVG unit 60 or the definition file for mapping the SVG document is displayed, and the cursor is displayed in the XHTML. When the document exists in the displayed area, a menu provided by the HTML unit 50 or a command defined in a definition file for mapping the XHTML document is displayed. Thereby, an appropriate user interface can be provided according to the editing position.

  If there is no appropriate plug-in or mapping definition file corresponding to a certain vocabulary in the compound document, the portion described by the vocabulary may be displayed in the source display or the tree display. Conventionally, when a compound document in which another document is embedded in one document is opened, the contents cannot be displayed unless an application for displaying the embedded document is installed. Even if there is no application for the purpose, the content can be grasped by displaying the XML document composed of the text data as a source or a tree. This is a characteristic unique to text-based documents such as XML.

  Another advantage of the data being described in the text base is that, for example, in a part described by a certain vocabulary in a compound document, data in a part described by another vocabulary in the same document can be referred to. Good. In addition, when a search is executed in a document, a character string embedded in a figure such as SVG can be a search target.

  A tag of another vocabulary may be used in a document described by a certain vocabulary. This XML document is not valid, but can be processed as a valid XML document if it is well-formed. In this case, the tag of another inserted vocabulary may be mapped by the definition file. For example, tags such as “important” and “most important” may be used in an XHTML document, and a portion surrounded by these tags may be highlighted, or may be sorted and displayed in order of importance. Good.

  When the document is edited by the user on the editing screen shown in FIG. 10, the plug-in or VC unit 80 in charge of the edited part changes the source tree. In the source tree, a listener for a mutation event can be registered for each node. Normally, a plug-in display unit or VC unit 80 corresponding to the vocabulary to which each node belongs is registered as a listener. When the source tree is changed, the DOM providing unit 32 traces from the changed node to a higher hierarchy, and if there is a registered listener, issues a mutation event to the listener. For example, in the document shown in FIG. 9, when a node below the <html> node is changed, a mutation event is notified to the HTML unit 50 registered as a listener in the <html> node, and the higher order node is also displayed. The mutation event is also notified to the SVG unit 60 registered as a listener in the <svg> node. At this time, the HTML unit 50 updates the display with reference to the changed source tree. The SVG unit 60 may ignore the mutation event because the node belonging to its own vocabulary has not been changed.

  Depending on the contents of editing, the overall layout may change as the display is updated by the HTML unit 50. In this case, the layout of the display area for each plug-in is updated by a configuration for managing the layout of the screen, for example, a plug-in responsible for displaying the top node. For example, when the display area by the HTML unit 50 becomes larger than before, the HTML unit 50 first draws a part that it is in charge of and determines the size of the display area. Then, the configuration managing the screen layout is notified of the size of the display area after the change, and the layout is requested to be updated. Upon receiving the notification, the configuration for managing the screen layout re-lays out the display area for each plug-in. In this way, the display of the edited part is appropriately updated, and the layout of the entire screen is updated.

  Here, the editing unit 24 will be described in detail. The editing unit 24 includes a hierarchical analysis unit (not shown). The editing unit 24 is a block for editing a document composed of partial documents respectively described by a plurality of tag sets having a specific hierarchical structure. The hierarchical analysis unit analyzes the hierarchical structure of the tag set relating to the read document. The editing unit 24 gives a command to the processing system that processes each tag set based on the analysis result. The editing unit 24 assigns a document display area for displaying the partial document to each partial document, displays the corresponding partial document in the document display area, and accepts editing of the partial document by the user.

  Here, the display control unit 110 will be described in detail. FIG. 11 is a diagram illustrating a configuration example of the display control unit 110 in FIG. The display control unit 110 includes a boundary display unit 112, a name display unit 114, a hierarchical structure display unit 116, an emphasis processing unit 118, a cursor position determination unit 120, and a menu display unit 122.

  The boundary display unit 112 displays the boundary of the document display area of the partial document. In addition, the boundary display unit 112 displays the boundary of the document display area 310 assigned to at least the partial document related to the tag set of the highest hierarchy among the partial documents to be edited by the editing unit 24. At this time, boundaries in all layers included in the partial document to be edited may be displayed together.

  The hierarchical structure display unit 116 displays, in parallel with the document edited in the editing unit, the names of processing systems related to tag sets of the respective layers analyzed by a hierarchical analysis unit (not shown) in the editing unit 24 on the same screen. Display in the hierarchy display area.

  The name display unit 114 displays the names of a plurality of files included in the document in the file name display area.

  The menu display unit 122 displays the name of the document editing function provided by the processing system for the tag set in the menu display area on the same screen according to the hierarchical structure analyzed by the hierarchical analysis unit of the editing unit 24. The menu display unit 122 also displays the name of the document editing function provided by the processing system related to the tag set in a higher hierarchy than the tag set corresponding to the partial document to be edited in the editing unit. May be. The menu display area includes an area for displaying a basic menu and a menu related to the plugged-in function. For example, the basic menu includes functions such as document saving, reading, word search, and replacement. The menu related to the plugged-in function includes a function for superscript, a function for summing up numerical values existing in a designated area, a macro function by a user, and the like.

  The cursor position determination unit 120 determines the position on the screen such as a pointer displayed by operating a mouse or the like when the user performs an editing process, or a cursor. The user moves the specified part of the multiple partial documents displayed on the screen by moving the pointer to the position where the partial document to be edited is displayed and depressing the mouse button. Documents can be edited. In the following, in order to simplify the explanation, “When the user performs the editing process, the mouse or the like is used to move the pointer displayed on the screen or the cursor to select a predetermined location. "Specify" is simply abbreviated as "specified by user" or "by user designation".

  When displaying the boundary of the partial document by the boundary display unit 112, the enhancement processing unit 118 displays it in an identifiable manner as compared with the boundaries of other document display areas. Further, with respect to the hierarchy of the partial document to be edited displayed on the hierarchical structure display unit 116, the hierarchy relating to the processing system corresponding to the partial document can be identified in comparison with the hierarchy relating to other processing systems. Display in the hierarchy display area. Further, for the partial document to be edited displayed in the name display unit 114, the name of the file corresponding to the partial document is displayed in the file name display area in such a manner that it can be distinguished from the names of other files. Further, when the name of the document editing function is displayed in the menu display unit 122, the name of the document editing function provided by the processing system corresponding to the partial document to be edited in the editing unit is displayed for other document editing functions. It is displayed in the menu display area in such a manner that it can be identified from the name.

  Here, the identifiable mode is, for example, displaying the boundary separately with a solid line and a broken line, or displaying the boundary line in different colors and shades, or changing the thickness of the boundary line. Including displaying. In addition, it may be displayed in a manner that can be identified by, for example, displaying it separately with a solid line and a broken line, and may be identified by displaying colors and shades with changes. It is good also as an aspect. Further, the background of one region may be drawn with a specific color or pattern so that the background of the other region is different. Moreover, it is good also as an aspect which can be identified by displaying one and not displaying the other.

  Further, the enhancement processing unit 118 compares the boundary of the document display area of the partial document corresponding to the hierarchy specified by the user with the boundary of other document display areas in conjunction with the display process performed by the hierarchical structure display unit 116. Display in an identifiable manner. Furthermore, the name of the corresponding file is also displayed in conjunction with the file name display area in an identifiable manner compared to the names of other files.

  The emphasis processing unit 118 can identify the boundary of the partial document corresponding to the name of the file specified by the user in comparison with the boundary of other partial documents in conjunction with the display process performed by the name display unit 114. Is displayed. Further, the hierarchy indicating the processing system related to the partial document corresponding to the designated file name is displayed in conjunction with the hierarchy display area in a manner that can be identified as compared with the hierarchy related to the other processing systems.

  The emphasis processing unit 118 also performs emphasis processing in the menu display area when the user performs a menu specifying operation. Specifically, during the menu designation operation by the user, it responds in conjunction with the highlighting processing for the partial document that has already been designated by the user, the hierarchy related to the partial document, or the file included in the partial document. Emphasis processing is also performed for the name of the document editing function provided by the processing system.

  With the above configuration, multiple partial documents displayed on the screen, the hierarchical structure of the processing system displayed in the hierarchy display area, or the file name displayed in the file name display area When the user designates any of the above, the corresponding partial document, hierarchy, and file name can be displayed so as to be clearly distinguishable from other displays. In addition, since it can be clearly distinguished from other displays, editing is facilitated and user convenience can be improved.

  Hereinafter, an example of a screen displayed as a result of the operation by the display control unit 110 will be described with reference to FIGS. First, the entire screen to be displayed will be described with reference to FIG. Next, the case where all the boundaries of each document are displayed in the document display area will be described with reference to FIG. Next, when any partial document is designated in the document display area using FIG. 12C and FIG. 12D, the corresponding hierarchy and the corresponding file are linked with the designation. A case where the name is displayed with emphasis will be described. Finally, a case where the document editing function provided by each processing system is displayed in the menu display area will be described with reference to FIG.

  FIG. 12A is a diagram illustrating a first display example of a screen displayed as a result of the operation of the display control unit 110 in FIG. In the first display example, the screen includes a launcher display area 300, a document display area 310, a hierarchy display area 320, a file name display area 330, and a first menu display area 342 represented by a menu display area 340. A second menu display area 344.

  It should be noted that the launcher display area 300 includes an area from the area where “Launcher” is displayed to the bottom of the screen. Further, the document display area 310 includes an area from the area where “Document View” is displayed to the bottom of the screen. Further, the hierarchical display area 320 includes an area from the area where “Components” is displayed to the bottom of the screen. Further, the file name display area 330 includes an area from the area where “Files” is displayed to the bottom of the screen.

  Further, the menu display area 340 is an area surrounded by a broken line in FIG. 12A, and is “File”, “Edit”, “Show”, “Favorite”, “Tools”, and the like. , “Help”, “Insert”, “Format”, “Section”, “Graph”, “Help”, and “Debug”. The first menu display area 342 is an area for displaying the basic menu in the menu display area 340. The basic menu includes “File”, “Edit”, “Show”, “Favorite”, “Tools”, and “Help”. The second menu display area 344 is an area for displaying plugged-in functions. Here, plugged-in functions include “Insert”, “Format”, “Section”, “Graph”, “Help”, and “Debug”.

  The launcher display area 300 is an area including a template display area 302, a bookmark display area 306, and a history display area 308. Here, the launcher includes a function for assisting editing of a document using various processing systems, and the launcher display area 300 includes an area for displaying a name of a function for assisting editing of the document.

  The template includes a tag set template. It can be said that the model is an editor of the tag set, and a tag set including a sentence can be created by describing the sentence directly in the document display area 310. The template display area 302 includes a name of a processing system related to a specifiable partial document and a check box indicating which processing system template is selected. For example, in FIG. 12A, SVG 303 and XHTML 304 are displayed as templates. Here, when the user designates a check box displayed on the left side of each display, the processing of the document to be edited in the document display area 310 is selected.

  The bookmark includes the name of the document stored by the user's designation at any point in time when editing the document by the user, or the position in the document, and is simply called “bookmark”. The bookmark display area 306 lists document names or document positions as line numbers or coordinates in the stored order. The history includes a time series of the fact that the user has edited the past or the fact that the user has performed specific processing among the editing of the document by the user, and is also simply referred to as “history”. In the history display area 308, the names of documents edited by the user in the past or the names of specific processes performed by the user are displayed in chronological order. Here, the specific process is, for example, a process for erasing any part of the document, a cut process to be stored for pasting, a paste process for pasting the stored part, or a new partial document. Including the process of adding. When the user designates one of the histories displayed in the history display area 308, a so-called undo process may be performed to return to the state of the process related to the designation.

  The document display area 310 is an area for displaying a document, and may display a document described by a plurality of tag sets, or may display a description of a tag set related to a processing system itself. . Further, the document display area 310 includes a display switch 328 for displaying the boundary of each partial document in the document display area 310. When the user designates the display switch 328, the presence / absence of the boundary display is switched. In FIG. 12A, since the mode in which the boundary is not displayed is “OFF”, the boundary is not displayed in the document in the document display area 310.

  The hierarchy display area 320 is an area for displaying the hierarchical structure of the document displayed in the document display area 310. The document displayed in the document display area 310 includes a plurality of partial documents, and each partial document is described by a corresponding tag set so as to be processed by a corresponding processing system. Individual tag sets may be hierarchized to have other tag sets within them. Here, what is displayed in the hierarchy display area 320 is the name of the processing system for processing the tag set. For example, in the hierarchical display area 320, names of six processing systems are displayed, and it is clearly indicated that the highest processing system is “HTML” in the first HTML 322.

  Further, two “SVGs” exist in the first SVG 323 and the third SVG 327 in the hierarchy immediately below “HTML” of the first HTML 322. In addition, “HTML” is present in the second HTML 324 below one of the first SVG 323. Furthermore, it is shown that “MathML” in the MathML 325 and “SVG” in the second SVG 326 exist in the layer below the “HTML” of the second HTML 324.

  Here, “−” and “+” displayed on the left side of each layer displayed in the layer display area 320 will be described. "-" Indicates that the processing system displayed on the right side has a lower hierarchy. “+” Indicates that the processing system displayed on the right side has a lower hierarchy, and that the lower hierarchy is not displayed in the hierarchy display area 320. In the case of “+”, the lower hierarchy can be displayed by the user's designation. In this case, the display of “+” changes to “−”. Further, the MathML 325 and the second SVG 326 in which neither “−” nor “+” is displayed indicate that there is no hierarchy lower than the hierarchy.

  In some cases, the partial document displayed in the document display area 310 includes an external file, or there is a partial document that is referred to. The file name display area 330 is an area for displaying the name of the external file in such a case. In FIG. 12A, a first file 335 and a second file 336 are displayed as two external files included in the partial document in the document display area 310.

  FIG. 12B is a diagram illustrating a second display example of a screen displayed as a result of the operation of the display control unit 110 in FIG. The second display example is an example in which the boundary of each partial document is displayed in the document display area 310. In other words, it can be said that the second display example is a display example in the case where the boundary of each partial document is displayed by setting the display switch 328 to “ON” in the first display example. The display of these boundaries is executed by the boundary display unit 112 in FIG. In addition, about the part same as Fig.12 (a), the same code | symbol is attached | subjected and description is abbreviate | omitted.

  In the second display example, the boundary is displayed in the document display area 310 for each partial document. In this boundary display, the first boundary 312, the second boundary 313, the third boundary 314, the fourth boundary 315, and the fifth boundary 316 are displayed by broken lines. Each boundary is also a boundary of a partial document. A partial document in the inner boundary indicates that a hierarchy relating to a tag set describing the partial document exists in the lower layer. For example, since the second boundary 313 exists inside the first boundary 312, the second boundary 313 is lower than the first boundary 312 in the hierarchy related to the corresponding partial document.

  In addition, when two or more boundaries exist within the same boundary, those layers are the same layer. For example, the fourth boundary 315 and the fifth boundary 316 are both present inside the third boundary 314, and the fourth boundary 315 and the fifth boundary 316 do not include the other, so both are the same. It becomes a hierarchy. Here, depending on the region defined in each tag set, the boundaries may overlap each other like the fourth boundary 315 and the fifth boundary 316. It may be determined by the description in the tag set as to which display within the boundary is to be preferentially displayed.

  Here, before describing FIG. 12C to FIG. 12E, the correspondence between each partial document displayed in FIG. 12B, the hierarchy, and the file will be described. The partial document inside the first boundary 312 corresponds to the first HTML 322. A partial document inside the second boundary 313 corresponds to the first SVG 323. A partial document inside the third boundary 314 corresponds to the second HTML 324. The partial document inside the fourth boundary 315 corresponds to the second HTML 324 and the first file 335. Further, the partial document inside the fifth boundary 316 corresponds to the second SVG 326 and the second file 336. Further, the partial document corresponding to the third SVG 327 is not displayed on the screen in FIG. 12A, and corresponds to the partial document displayed by the user scrolling the screen. In the following, a display example of a screen under the above-described correspondence will be described.

  FIG. 12C is a diagram illustrating a third display example of the screen displayed as a result of the operation of the display control unit 110 in FIG. In addition, about the part same as Fig.12 (a), the same code | symbol is attached | subjected and description is abbreviate | omitted.

  The third display example shows names of a plurality of partial documents displayed in the document display area 310, a plurality of processing systems displayed in the hierarchy display area 320, or a plurality of files displayed in the file name display area 330. It is a display example about the highlight when a user designates either. Here, an example will be described in which the boundary, hierarchy, and file name of each corresponding partial document are highlighted and displayed in conjunction with user designation. Note that description will be made assuming that the display switch 328 is “ON”. The enhancement processing described below is performed by the enhancement processing unit 118 for the corresponding display according to the determination by the user position designated by the cursor position determination unit 120 of FIG. 11 being determined.

  Here, it is assumed that MathML 325 in the hierarchy display area 320 is designated by the user. In this case, first, MathML 325 in the hierarchy display area 320 is displayed with emphasis. Here, as an example of emphasis display, a hexagon representing the processing system of MathML 325 is provided with a pattern composed of a plurality of oblique lines. Further, in conjunction with this highlighting, the fourth boundary 315 of the corresponding partial document in the document display area 310 is highlighted and displayed. Here, the emphasis process is performed in such a manner that the fourth boundary 315 is displayed with a broken line and the other boundary is not displayed with a broken line. In the file name display area 330, the corresponding first file 335 is highlighted in conjunction. Here, in order to clarify the correspondence with the enhancement processing of MathML 325, the same enhancement processing is performed. Note that both the fourth boundary 315 and the other boundary may be displayed with solid lines, and the solid line of the fourth boundary 315 may be represented with a color that can be distinguished from the other boundaries. Further, the fourth boundary 315 may be displayed as a solid line, and the other boundary may be displayed as a broken line.

  In addition, when the user designates any partial document displayed in the document display area 310, the partial document becomes an editing target, and the user can edit the partial document. Similarly, when the user designates any one of the hierarchies displayed in the hierarchy display area 320 or any one of the files displayed in the file name display area 330, the partial document corresponding to the designation is emphasized. Displayed and ready for editing. Further, when the user designates any one of the partial document, the hierarchy, and the file, a menu provided by the corresponding processing system is displayed in the second menu display area 344.

  FIG. 12D is a diagram illustrating a fourth display example of a screen displayed as a result of the operation of the display control unit 110 in FIG. In addition, about the part same as Fig.12 (a), the same code | symbol is attached | subjected and description is abbreviate | omitted.

  As in the case of FIG. 12C, the fourth display example is a plurality of partial documents in the document display area 310, a plurality of processing systems in the hierarchy display area 320, or a plurality of files in the file name display area 330. It is an example of a display about emphasis display when the user designates any of the names. Here, a display example is shown for the case where the user designation is for a hierarchy that is not the lowest layer in the hierarchical structure. Specifically, for the specified hierarchy and the hierarchy below the hierarchy, the boundaries of the partial documents corresponding to each hierarchy are displayed together. Note that description will be made assuming that the display switch 328 is “ON”. The enhancement processing described below is performed by the enhancement processing unit 118 for the corresponding display according to the determination by the user position designated by the cursor position determination unit 120 of FIG. 11 being determined.

  Here, it is assumed that the second HTML 324 in the hierarchical display area 320 is designated by the user. In this case, first, the second HTML 324 in the hierarchical display area 320 is highlighted and displayed. Further, the enhancement processing is similarly performed on the MathML 325 and the second SVG 326 existing below the second HTML 324. Here, as an example of highlighting, a hexagon representing a processing system of the second HTML 324 is provided with a pattern composed of a plurality of oblique lines. In addition, MathML 325 and second SVG 326 that similarly perform enhancement processing are displayed in a manner that is different from the second HTML 324 so that each can be identified separately.

  Further, in conjunction with this highlighting, the third boundary 314 of the corresponding partial document in the document display area 310 is highlighted and displayed. Further, enhancement processing of the fourth boundary 315 and the fifth boundary 316 corresponding to the MathML 325 and the second SVG 326 existing below the second HTML 324 is performed together. Here, the boundary of the third boundary 314 is displayed as a solid line, and the boundary of the fourth boundary 315 and the fifth boundary 316 is displayed as a broken line, thereby distinguishing each. In addition, it is good also as an aspect which can be identified by displaying only the 3rd boundary 314 of the 3rd boundary 314 concerning the designated hierarchy, and not displaying the 4th boundary 315 and the 5th boundary 316 concerning a lower layer.

  In the file name display area 330, the first file 335 corresponding to the MathML 325 is highlighted in conjunction with the file. Further, the second file 336 corresponding to the second SVG 326 is emphasized in conjunction with the second file 336. Here, in order to clarify the correspondence with the enhancement processing with MathML 325 and the second SVG 326, the same enhancement processing is performed respectively.

  FIG. 12E is a diagram illustrating a fifth display example of a screen displayed as a result of the operation of the display control unit 110 in FIG. In addition, about the part same as Fig.12 (a), the same code | symbol is attached | subjected and description is abbreviate | omitted.

  In the fifth display example, similarly to FIG. 12D, a plurality of partial documents displayed in the document display area 310, a plurality of processing systems displayed in the hierarchy display area 320, or a file name display area 330 are displayed. It is a display example about the highlighting when the user designates one of the names of a plurality of displayed files. Here, the menu display when any one of the second menu display areas 344 is designated by the user will be described. Specifically, the name of the document editing function provided by the processing system corresponding to each hierarchy is displayed for the designated hierarchy and the hierarchy higher than that hierarchy. Note that description will be made assuming that the display switch 328 is “ON”. In addition, the display processing described below is performed by the menu display unit 122 for the corresponding display according to the determination by the user position designated by the cursor position determination unit 120 of FIG. 11 being determined. The enhancement processing is performed by the enhancement processing unit 118.

  Here, it is assumed that the processing system designated by the user is the second HTML 324, and after the designation, “Format” is designated among the document editing functions displayed in the second menu display area 344. In this case, first, the third menu display area 346 is displayed immediately below the second menu display area 344. In the third menu display area 346, an Arrange function 348 and an Indent function 349 are displayed as document editing functions. In addition, a Style function 347 is also displayed in the third menu display area 346 as a document editing function provided by the first SVG 323 that is a higher processing system of the second HTML 324 according to the user's designation.

  By displaying the document editing function related to the upper processing system, it is possible to obtain an effect that a document related to the lower processing system can be directly edited. For example, if you want to change the typeface of all the documents related to the lower level processing system at once, or if you want to rotate and display the document itself, it is more accurate to process it collectively than to process each partial document. This leads to a reduction in cost and time cost.

  In this case, the Arrange function 348 and the Indent function related to the processing system designated by the user are displayed in a manner distinguishable from the third menu display area 346. Here, identification is made possible by displaying in the form of underlining the names of the Arrange function 348 and the Indent function 349.

  The characteristics of the document processing technique in the present embodiment are summarized as follows. Of the documents displayed on the screen, by displaying the boundary of the document designated by the user in an identifiable manner, the boundary with other documents can be clearly distinguished. In addition, since the boundary with other documents can be clearly distinguished, editing is facilitated and user convenience can be improved. By the user specifying one of multiple partial documents displayed on the screen, the hierarchical structure of the processing system displayed in the hierarchy display area, or the file name displayed in the file name display area The corresponding partial document, hierarchy, and file name can be displayed so that they can be clearly distinguished from other displays. In addition, since it can be clearly distinguished from other displays, editing is facilitated and user convenience can be improved. In addition, it becomes easier to maintain data consistency of document files handled in business organizations such as companies, and costs can be reduced.

  In the above, this invention was demonstrated based on the Example. This embodiment is an exemplification, and it will be understood by those skilled in the art that various modifications can be made to the combination of each component and each processing process, and such modifications are also within the scope of the present invention. .
