Wow, that's good!

I certainly have NOT been working on it.

In relation to DOM, there is already jython/java support in the current 
PyXML, in the shape of an adapter library which provides a pythonic API 
for common java DOMs.

http://pyxml.cvs.sourceforge.net/pyxml/xml/xml/dom/javadom.py

I submitted a patch a couple of years ago that updated that module to 
include JAXP.

As Samuele mentions in relation to that patch, it should really be 
submitted to the PyXML project, which is where it belongs.

Really, xml-sig is the place to be discussing these issues, since it is 
the pyxml codebase that needs to change, not the jython codebase.

I think that most people who use standard SAX and DOM in jython use the 
java versions instead: I do so myself.

But it would be nice to be able to write the same code to run on both 
cpython and jython.

There are other things that would be nice to integrate. For example, it 
would be nice to use the excellent (OM-independent) jaxen.org Xpath 
library to implement an Xpath API that is compatible with PyXML xpath api.

I think we would need to be fairly clear on what would achieved by 
bringing PyXML up-to-date with the latest jython. Would code that uses 
PyXML run seamlessly across cpython and jython? (Excluding 2.2 vs. 
2.{3|4|5} differences.) For what components of PyXML? SAX? DOM? Xpath?

Maybe we need a wiki page to discuss what the goals might be?
