Second, I've read the docs and see a lot of examples for building trees, but not a lot for traversing parsed trees. Questions: 1. Is there a good idiom for namespaces? I'm currently doing things like: UML='{href://org.omg/UML/1.3}' .... packages=ns2.findall(UML+'Package') 2. Is there a similar idiom which works for Paths? I've tried: packages=pkg1.findall(UML+'Namespace.ownedElement/'+UML+'Package') but haven't found the right combination, so I do step-at-a-time descent. -- [EMAIL PROTECTED] 6-6M21 BCA CompArch Design Engineering Phone: (425) 294-4718 -- http://mail.python.org/mailman/listinfo/python-list
