Also, as noted elsewhere in the string, your C is actually a list of
Cs. So replace my else statement with
return [(child[0], reduceXML(child[2])) for child in node]
I think that'll do what you need. However, I'm not sure why you need
to. You're not getting any new information out of your data structure.
Why not just ignore the attributes and the spare tuplet (or whatever you
call tuple-items) when you do the real processing next time through?
