Commented: (DOXIA-24) [PATCH] better docbook support through the use of docbook xsl stylesheets

    [ ]

Jose Gonzalez Gomez commented on DOXIA-24:

There was some talk a while ago about this issue in the lists. As far as I remember, the conclusion was that a separate docbook plugin would be desirable, and support for Docbook in Doxia should be kept to a minimum.

Anyway feel free to do whatever you want with my code.

> The current state of DocBook support in Doxia is still unsatisfactory. It is now able to handle the most important elements, but there is still an important problem left out: handling of xref-links. This type of links points to another docbook element and is expected to be replaced with a text describing the element by the processing system. For example an xref pointing to a chapter would be replaced with the text "Chapter N: 'Title of Chapter N'". Implementing this functionality using the XML Pull Parser currently used in Doxia is a massive effort because it leads to duplicating a lot of functionality already available in the DocBook XSL Stylesheets, the standard solution for processing DocBook XML and involves caching of more or less the whole DocBook document.
> My proposed solution is simple, elegant, but quite heavyweight: I use the DocBook XSL Stylesheets (which will be bundled with the doxia.jar) and transform the DocBook input document into a temporary XHTML document. The stylesheets are driven by a customization layer that turns off any unnecessary features like autogenerated tables of contents and navigation graphics.
> The temporary XHTML document is processed by the Doxia's XhtmlParser into a DoxiaModel. The DocBook XSL stylesheets and the XhtmlParser take care of maintaining the section nesting of the document, so that no important information will be lost.
> If the DocBook DTD changes, no Java programming is neccessary, all you need to do is updating the enclosed DocBook XSL stylesheets. The system is able to handle all of the DocBook elements and offers all advanced features of the DocBook XSL stylesheets like autogenerated texts and so on.
> There is only one major drawback: Parsing the DocBook stylesheets takes an huge amount of memory, but it is still possible to run maven with the default java heap space.
