Abstract

Markup language stylizations that may be applied to a source document are defined in overlay documents such that no special tags or markers are required in the source document to enable stylization via the overlay document. A manifest document defines an association between a source document and one or more overlay documents.

Claims

1. A method, comprising:

receiving a request for a markup language source document;

identifying a manifest document associated with the requested source document;

determining an overlay document to be applied to the source document as specified by the manifest document;

generating a modified source document by applying the overlay document to the requested source document; and

in response to the request, returning the modified source document.

2. The method as recited in claim 1, wherein identifying a manifest document comprises determining that a filename associated with the source document matches a filename specified in the manifest document, wherein the filename specified in the manifest document includes at least one wildcard character.

3. The method as recited in claim 1, wherein identifying a manifest document comprises:

determining that a filename associated with the source document matches a filename specified in the manifest document; and

determining that an attribute of the source document fulfills an attribute condition specified in the manifest document.

4. The method as recited in claim 1, further comprising:

maintaining a copy of the modified source document;

receiving a second request for the source document; and

in response to the second request, returning the copy of the modified source document.

5. The method as recited in claim 1, further comprising:

maintaining a copy of the modified source document;

receiving a second request for the source document;

determining that the source document has been edited since the modified source document was generated;

generating a new modified source document by applying the overlay document to the source document that has been edited; and

in response to the second request, returning the new modified source document.

6. The method as recited in claim 1, further comprising:

maintaining a copy of the modified source document;

receiving a second request for the source document;

determining that the overlay document has been edited since the modified source document was generated;

generating a new modified source document by applying the overlay document that has been edited to the source document; and

in response to the second request, returning the new modified source document.

7. A system, comprising:

a source document having hypertext markup language (HTML) content;

an overlay document having extensible hypertext markup language (XHTML) content that specifies changes that may be made to an HTML document; and

a manifest document that defines a relationship between the source document and the overlay document such that the overlay document can be used to stylize or otherwise modify the source document.

8. The system as recited in claim 7, wherein the overlay document has a version, and the source file specifies an overlay version with which the source file is compatible.

9. The system as recited in claim 7, wherein the source document comprises a section of HTML content that is designated as immutable to prevent modification via the overlay document.

10. The system as recited in claim 7, wherein the source document comprises a section of HTML content that is designated as modifiable such that the overlay document may only modify the designated section of HTML content.

11. The system as recited in claim 7, wherein the overlay document, when applied to the source document, modifies an element'"'"'s content in the source document.

12. The system as recited in claim 7, wherein the overlay document, when applied to the source document, modifies an attribute of an element in the source document.

13. The system as recited in claim 7, wherein the overlay document, when applied to the source document, rearranges elements to modify a structure of the source document.

14. The system as recited in claim 7, wherein the overlay document is contained within the manifest document.

15. One or more computer-readable media comprising computer-executable instructions that, when executed, direct a computing system to:

identify an overlay document to be applied to a source document;

generate a landmark hierarchy based on the overlay document, where each landmark represents an element that may be present in the source document;

step through elements in the source document to identify an element that corresponds to a first landmark in the landmark hierarchy;

identify an overlay directive associated with the fist landmark; and

generate a modified element by applying the overlay directive to the element that corresponds to the first landmark in the landmark hierarchy.

16. The one or more computer-readable media as recited in claim 15, further comprising computer-executable instructions that, when executed, direct the computer system to copy the source document to a modified source document, replacing the element that corresponds to the first landmark in the landmark hierarchy with the modified element.

17. The one or more computer-readable media as recited in claim 15, wherein the overlay directive comprises instructions to modify contents of the element.

18. The one or more computer-readable media as recited in claim 15, wherein the overlay directive comprises instructions to modify an attribute of the element.

19. The one or more computer-readable media as recited in claim 15, wherein the overlay directive comprises instructions to modify a location of the element within the source document.

20. The one or more computer-readable media as recited in claim 15, wherein the overlay directive comprises instructions to remove the element from the source document.
