Take a look at the new pywxrc tool in CVS.

http://cvs.wxwidgets.org/viewcvs.cgi/wxWidgets/wxPython/wx/tools/pywxrc.py

It now generates a Python module with a base class for each top-level 
item in the XRC that loads itself from the resource and also has code 
like "self.Item = xrc.XRCCTRL(self,'Item')" for every named item.

Any XML parser can do it.  That's all that pywxrc uses.
