Abstract

Systems, methods and computer program products are provided for utilizing XML-based tools to tailor HTML-based Web page content for display within various client devices. Content portions of a requested Web page are converted to an XML format and then modified using an XML content-tailoring tool. Other content portions of the Web page are masked so as to be “hidden” and are, thus, not converted to XML format. The masked portions of the Web page are then unmasked, combined with the modified content portions, and transmitted to a client device for display therewithin.

Claims

1. A method of tailoring Web page content for display via a client device, wherein the Web page contains a first content portion in HyperText Markup Language (HTML) format that can be converted into Extensible Markup Language (XML) format, the method comprising the following steps:

receiving a request from the client device for the Web page;

converting the first content portion from HTML format to XML format;

modifying the converted first content portion for display within the client device using a content tailoring tool in XML format; and

converting the modified first content portion from XML format to HTML format.

2. A method according to claim 1 further comprising the step of transmitting the Web page containing the modified first content portion to the client device for display therewithin.

3. A method according to claim 1 wherein the Web page contains a second content portion in HTML format that is difficult to convert into XML format, and further comprising the step of masking the second content portion from view of the content tailoring tool prior to the step of modifying the converted first content portion.

4. A method according to claim 3 further comprising the step of unmasking the second content portion prior to the step of transmitting the Web page containing the modified first content portion to the client device.

5. A method according to claim 1 wherein the Web page contains a third content portion in HTML format that does not require modification for display within the client device, and further comprising the step of masking the third content portion from view of the content tailoring tool prior to the step of modifying the converted first content portion.

6. A method according to claim 5 further comprising the step of unmasking the third content portion prior to the step of transmitting the Web page containing the modified first content portion to the client device.

7. A method according to claim 1 wherein the step of modifying the converted first content portion for display within the client device is performed via an XML parser.

8. A method according to claim 1 wherein the step of modifying the converted first content portion for display within the client device is performed via an Extensible Style Language (XSL) processor.

9. A method according to claim 1 wherein the client device is a pervasive computing device.

10. A method of tailoring Web page content for display via a client device, wherein the Web page contains a first content portion in HyperText Markup Language (HTML) format that can be converted into Extensible Markup Language (XML) format, and a second content portion in HTML format that is difficult to convert into XML format, the method comprising the following steps:

receiving a request from the client device for the Web page;

converting the first content portion from HTML format to XML format;

masking the second content portion from view of an XML content tailoring tool;

modifying the converted first content portion for display within the client device using an XML content tailoring tool;

converting the modified first content portion from XML format to HTML format;

unmasking the second content portion; and

transmitting the Web page containing the modified first content portion to the client device for display therewithin.

11. A method according to claim 10 wherein the Web page contains a third content portion in HTML format that does not require modification for display within the client device, and further comprising the step of masking the third content portion from view of the XML content tailoring tool prior to the step of modifying the converted first content portion of the Web page.

12. A method according to claim 11 further comprising the step of unmasking the third-content portion prior to the step of transmitting the Web page containing the modified first content portion to the client device.

13. A method according to claim 11 wherein the step of modifying the converted first content portion for display within the client device is performed via an XML parser.

14. A method according to claim 11 wherein the step of modifying the converted first content portion for display within the client device is performed via an Extensible Style Language (XSL) processor.

15. A method according to claim 11 wherein the client device is a pervasive computing device.

17. A system according to claim 16 further comprising means for transmitting the Web page containing the modified first content portion to the client device for display therewithin.

18. A system according to claim 16 wherein the Web page contains a second content portion in HTML format that is difficult to convert into XML format, and further comprising means for masking the second content portion from view of the content tailoring tool prior to modification of the converted first content portion.
