Abstract

A method and system are provided for processing a hypertext markup language (HTML) source file stored in a server processor. The processing is performed by a browser program in a client processor. The server processor and client may communicate with each other across a communications network, which may be the Internet. The HTML source file may define a web page in the worldwide web. The browser, in the client processor, processes the source file to generate an output display. A region within the output display is selected using a pointing device, such as a mouse, track ball, or the like. The region includes less than the whole output display. The region includes information, which may include text, a list, a table, or a graphic. Information that is displayed within the region is identified by the client processor. The client processor identifies a portion of the source file from which the information displayed within the region is generated. The portion is less than the whole source file. The identification includes a search for matching text in the region and in the portion of the source file. The HTML tags in the source file are examined to determine whether they are the appropriate tags to generate the information in the region. The identified portion of the source file is output by the client processor.

Claims

1. A method for separating a source file sent by a server in a network into subfiles, comprising the steps of:

(a) processing the source file to generate an output display;

(b) selecting a region within the output display, the region including less than the whole output display and containing an arbitrary area of the output display;

(c) identifying information that is displayed within the region;

(d) identifying a portion of the source file from which the information displayed within the region is generated, the portion representing one subfile of the source file;

(e) obtaining code for the one subfile; and

(f) outputting the code.

2. The method according to claim 1, wherein the source file is a hypertext markup language source file and the portion of the source file includes hypertext markup language tags.

3. The method according to claim 2, wherein the information includes at least one of text, a list, and a table.

4. The method according to claim 2, wherein the information includes a list containing text and step (d) includes:

(d1) searching for any text within the source file which matches the text within the region, and

(d2) if a subset of the text within the source file matches the text within the region, determining whether the hypertext markup language tags in the source file, which are associated with the text in the subset, are hypertext markup language tags for defining a list.

5. The method according to claim 2, wherein the information includes a table containing text and step (d) includes:

(d1) searching for any text within the source file which matches the text within the region, and

(d2) if a subset of the text within the source file matches the text within the region, determining whether the hypertext markup language tags in the source file, which are associated with the text in the subset, are hypertext markup language tags for defining a table.

6. The method according to claim 1, wherein step (a) includes the step of viewing the source file via a web browser.

7. The method according to claim 1, wherein the information includes a graphic.

8. The method according to claim 1, wherein steps (a) through (e) are performed by a client processor and the source file is stored in a server processor separate and distinct from the client processor.

9. The method according to claim 8, wherein the client processor and the server processor are connected via a communications network.

10. The method according to claim 1, wherein the source file contains one of source and object code of a software program and step (d) includes the steps of:

(da) determining an output of the software program, and

(db) identifying one of the source and object code of the software program as the portion of the source file if the output of the software program matches the information displayed within the region.

11. The method according to claim 10, wherein the source file contains Java code.

12. The method according to claim 1, wherein the source file references a further file containing one of source and object code of a software program;

step (d) includes the steps of (1) determining an output of the software program, and (2) determining whether the output of the software program matches the information displayed within the region; and

the method further includes the step of (f) listing one of the source and object code of the software program if the output of the software program matches the information displayed within the region.

13. The method according to claim 12, wherein steps (a) through (e) are performed by a client processor, and the further file is stored in a server processor separate and distinct from the client processor.

14. The method according to claim 13, wherein the server processor includes a language library, and step (1) includes the step of using the language library to determine the output of the software program.

15. The method according to claim 12, wherein the further file contains Java code.

16. A system for separating a source file sent by a server in a network into subfiles, the system comprising:

means for processing the source file to generate an output display;

means for selecting a region within the output display, the region including less than the whole output display and containing an arbitrary area of the output display;

means for identifying information that is displayed within the region;

means for identifying a portion of the source file from which the information displayed within the region is generated, the portion representing one subfile of the source file;

means for obtaining code for the one subfile; and

means for outputting the code.

17. A computer-readable medium for use in a computer system having a display, the computer readable medium encoded with a computer program for separating a source file sent by a server in a network into subfiles, the computer readable medium comprising:

(a) means for causing the computer to process the source file to generate an output display;

(b) means for causing the computer to receive an identification of a region within the output display, the region including less than the whole output display and containing an arbitrary area of the output display;

(c) means for causing the computer to identify information that is displayed within the region;

(d) means for causing the computer to identify a portion of the source file from which the information displayed within the region is generated, the portion representing one subfile of the source file;

(e) means for causing the computer to obtain code for the one subfile; and

(f) means for causing the computer to output the code.
