Heres some test code I was playing with a while back...
(shout out to Nicole for helping me with it ;-)

Note this uses MS XML and ASPTear COM object. The reason is that the XML 
COM Object has a nasty parsing bug. You need to strip the DOCTYPE in order 
for the XML to parse correctly. If you install the newest XML COM Object, 
you can use the new COM object without ASPTear and the ugly hack I used.

You can get the new XML Object here (watch for wrap):
