Hi Stefan,
Thanks for the excellent pointer to xml.etree.ElementTree: it sure makes life 
easier :-)
Bye,
Ron.

This is my first try at XML with Python, and though I tried to read on the web, 
I'm unable to traverse a DOM tree, as my top element seems to be DOCUMENT_NODE 
and I cannot find a way to get to the nodes below it.


You might find the xml.etree.ElementTree package a lot easier to work with.



$ python -u xml_parse.py
node:
dom2.nodeType: 9
dom2.nodeName: #document
node is DOCUMENT_NODE:
node:
dom2.nodeType: 9
dom2.nodeName: #document
node is DOCUMENT_NODE:
('dom2._get_childNodes():', [,])
Traceback (most recent call last):
   File "xml_parse.py", line 26, in
 print("child_nodes._get_childNodes():",child_nodes._get_childNodes())
AttributeError: 'NodeList' object has no attribute '_get_childNodes'


"childNodes" is a property, use it like

print("child_nodes.childNodes:", child_nodes.childNodes)

By convention, the underscore at the beginning of "_get_childNodes" 
indicates that it is not considered a public method.
