XPointer and XPath implementation
Hi all,
I am investigating implementing XPointer in the existing XInclude feature,
and have found org.apache.xerces.impl.xpath.XPath and
org.apache.xerces.impl.xs.identify.XPathMatcher.
Before I launch into major code development, I'd appreciate any thought
about how (or whether) these class can be extend to provide XPath for
XPointer. I guess my major question is how to extend XPath to add the
additional functions that XPointer provides.
Regards
Dean

Actually, the changes on the XInclude spec are rather minor. Basically,
instead of having the XPointer specified as a fragment identifier, it is
handled as a separate attribute.
This is what we had to do to satisfy some rather obscure theoritical
problems with the fragment id.

You probably want to hang tight for a couple of weeks. The W3C
working group is preparing a major new working draft of XInclude
which will substantially revise how XPointers are handled. If I were
you I'd want to see this before beginning a lot of work I might have
to throw out.
