  • a World Wide Web (WWW) site typically consists of a collection of HyperText Markup Language (HTML) documents.
  • HTML is a text language that provides for hyper-linked graphic display.
  • a user of a Web browser utilizing the World Wide Web (WWW) typically requests that a Web server download HTML text to his Web browser.
  • the Web browser interprets the downloaded HTML text and generates screen images from the HTML text.
  • the HTML text invariably describes hyper-linked hot spots, that cause further downloads when selected.
  • FIG. 2 is a flowchart illustrating construction of parsed HTML file by a parser interpreting an original HTML file, as shown in FIG. 1 ;
  • FIG. 1 is a block diagram of a data processing system, in accordance with the present invention.
  • Original HTML text 40 stored on disk is parsed by a parser 42 into parsed HTML (PHTML) text 44, again stored in a Non- Volatile Storage Medium.
  • the parser sequentially interprets the original HTML text 40. Sequences of static HTML commands are collected into static HTML records, and sequences of active or dynamic HTML commands are collected into dynamic HTML records. These variable length static and dynamic HTML records are then written to the parsed HTML (PHTML) text 44 file stored in a Non-Volatile Storage Medium.
  • variable length record formats Many computer architectures directly support variable length records. In these architectures, it would most often be preferable to utilize a standard variable length record format.
  • SDF System Data Format
  • VAX systems by Digital Equipment Corporation support a similar variable length record format.
  • Count key data records provide a variable record length format on International Business Machines.
  • One alternate embodiment is to store the parsed HTML (PHTML) 44 as variable length records in a database. Instead of interpreting the first couple of bytes in each record to determine whether it contains static or dynamic HTML, a flag can be included in each database record for this purpose.
  • the original HTML file 40 is opened (not shown) and a loop is entered.
  • the next HTML command is read, step 52.
  • a test is then made whether the HTML command just read is of the same type, static or dynamic, as the HTML commands being accumulated, step 54. If the type of the HTML command just read, step 52, is different from the type of HTML commands being accumulated, a record containing the HTML commands being accumulated is completed and written out to the parsed HTML file 44, step 56. A new record is then started to accumulate the type of HTML commands just read, step 58. In any case, the HTML command just read, step 52, is then added to the record under construction, step 60. A test is then made whether there is any more input, step 62.
  • FIG. 3 is a flowchart illustrating operation of a Web server 46 interpreting parsed HTML 44, as shown in FIG. 1.
  • the Web server 46 opens the parsed HTML file 44 and enters a loop. Within the loop, the next record descriptor is read, step 72. A test is then made whether there are more records in the file, step 74. This is typically a test for end-of-file. Most modern computer architectures automalically provide such an indication. If the end-of-file has not been detected, step 76, a test is made whether the record contains dynamic HTML, step 80. In the preferred embodiment, interpreting the start of the first HTML command in the next record does this. However, other types of record formats would require correspondingly different types of testing.
  • step 82 the HTML in the record is processed, step 82. This typically results in database accesses in response to the HTML commands, with the results of the database queries being transmitted to the Web browser on the client computer 48. Otherwise, when static HTML is being processed, the entire record is transmitted to the Web browser executing on the client computer 48 without interpretation by the server computer 46, step 84. In either case, the loop is then repeated, starting with reading the next record descriptor, step 72. When no more records remain to be processed, step 74, end-of-file processing is performed, step 86. A record length of zero may be transmitted at this point to indicate end-of-file to the Web browser on the client system 48.

  • FIG. 5 is a sample sequence of parsed HTML (PHTML) 44 generated from the sample HTML 40 in FIG. 4.
  • the first section of the original HTML 40 contains static HTML commands.
  • a record length of "0288" bytes is inserted before these static HTML commands. This is followed by an active or dynamic set of HTML commands. These are preceded by a length of "0059" in the parsed HTML 44.
  • a second set of static HTML follows, proceeded by a length of "0281" in the parsed HTML 44.
  • the parsed HTML 44 is terminated by a record length of "0000".

  • External Storage 32 includes machine-readable media such as floppy disks, removable hard drives, magnetic tape, CD-ROM, and even other computers, possibly connected via a communications line 28.

Abstract

Un programme d'interprétation (42) commence par analyser des scripts de langage HTML source (40) correspondant à des pages Web actives ou dynamiques, les convertissant en séquences statiques et dynamiques. Ces séquences statiques et dynamiques de HTML sont écrites sous forme d'enregistrements de longueur variable dans un fichier HTML analysé (44), chaque enregistrement étant entièrement constitué de commandes HTML statiques ou dynamiques. Un serveur de base de données (46), en réponse à une demande émanant de l'explorateur Web d'un ordinateur client (48), lit le HTML analysé, transmettant (47) sans interprétation des enregistrements HTML statiques audit explorateur (48) tout en interprétant les enregistrements HTML dynamiques et en exécutant des actions demandées de base de données (45) avant de transmettre (47) les résultats à l'explorateur.
