Although it was written to meet my own simple needs, I suggest you take a look 
at libxml2dom:

http://www.python.org/pypi?:action=display&name=libxml2dom

It should be possible to feed DOM nodes from libxml2dom into PyXML's XPath 
implementation, although I suppose I ought to wrap the libxml2 XPath 
functionality itself in order to be able to drop that particular dependency 
on PyXML. I did hear something about 4Suite and XPath convenience methods on 
nodes, and that did make me wonder if some kind of standard might emerge that 
I could implement in libxml2dom.

Anyway, I've been using libxml2dom with libxslt without unnecessary 
serialisation, so this may be what you're looking for. If you and others want 
to improve the software, I may establish a SourceForge project for it and let 
development follow that course.
