anyway I promise I'll soon make my patch work but I was reading Bruce Eckel blog, i'm not sure if you know him but he is a big guy in Java and recently has move to python a LOT, basically he did what your code does :) maybe you want to make a post there telling him of ur code.

Ok, so I started playing with your patch.
I made a couple changes to get it closer to working
(most of the diff makes formatting consistent, sorry)
The important changes are:
1. call _createTree through self
2. add an argument to _createTree, which is a reference to the
current node object (and Element doesnt have the XMLAttrs attribute ;-)
Line 76: self._createTree( rootNode, self )
Line 79: def _createTree( self, node, obj ):
Line 80: for attr, value in obj.XMLAttrs.iteritems ():
Line 83: if isinstance( v, XMLNode ) or inspect.isclass( v ) and
issubclass( v, XMLNode ):
Line 85: elif isinstance( v, XMLValue ):
But, for some reason, it is recursing infinitely (boy was that looooong
backtrace scrolling up my screen fun)
Unfortunately the message is useless, and I don't know anything about
ElementTree to understand the details of what your code does at the moment.
