Many thanks Dieter, works a treat.
I'm working through the python tutorial now.

"IndexError -- list index is out of range" tells you that
this is not a "nodeValue" problem.
Almost surely, you got a node without "childNodes". Then
"node.childNodes" will result in an "IndexError".
Thus, you will need to check for this situation (in a way
similar to checks for an empty "nodes" list).

This should tell you in which line of "get_attributes" the problem was.
As your mail agent decided to reformat the code (oh this Outlook :-( ),
and you did not number the line, I cannot tell you -- but I guessed above
(and probably not too bad)...
