Yes, thank you for your tip.

Shouldn't it work with minidom?

>>> import xml.dom.minidom
>>> doc = xml.dom.minidom.parseString("<section xlmns:mb='http://123' 
mb:name='abc'/>")
>>> doc.childNodes[0].getAttributeNS(u'http://123', u'name')
''

I was developing using Python 2.1 and 4Suite and the wsdllib.py library (which 
requires Ft.Lib.pDomlette).  When I downloaded the 2.2 4Suite Windows 
installer, there was no pDomlette.py.  

I suppose I could have used the 0.11 version with Python 2.2 on Windows, but 
it wasn't clear and (at the time) it seemed like a good idea to create a 
small file that reads wsdl and makes soap calls and works with native python 
libraries.

I've seen many of these before, thank you for all your work!

Hmmm, "Waiting for a reply" ...
