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

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). >and the traceback says "Module None, line 7 in get_attributes" is the cause. 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)... -- Dieter _______________________________________________ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
