Ah maybe you're confused about how text nodes work in minidom. Every element 
will have a nodeName attribute (not callable) but if you try el.nodeValue on 
a text node you get None. That's because the text is represented by a child 
node with nodeName '#text', so you want (el.nodeName, 
el.firstChild.nodeValue).

General tips - try the docs: 
http://docs.python.org/library/xml.dom.minidom.html
and also use dir() a lot on objects when you're learning a new api.

Hope that helps. Disclaimer: haven't used minidom in anger for some time.

Confused?  That's an understatement.  Part of the problem is that it's been 
a long time since I learned DOM and now I'm trying to cram to get this 
program done.

Anyway, your suggestion to access el.firstChild.nodeValue did the trick.

Thanks
