Thanks, although that thread didn't seem to resolve the issue. All the
first few links talk about is how to hack your own parser to make sense
of the Clark notation.
The problem at hand is with how Elementtree outputs namespaces and
represents the tag name in memory.
Given xml with no namespaces, Elementtree works perfectly. However, if
you give the root tag an xmlns attribute, Elementtree relabels all child
nodes with it's own prefix, completely defeating the purpose of the
default namespace. In my opinion, this is unacceptable behavior.
If an XML parser reads in and then writes out a document without having
altered it, then the new document should be the same as the original.
With Elementtree this isn't so. Lundh apparently believes he knows
better than you and I on how our namespaces should be represented.
It's a shame the default ns behavior in Elementtree is in such a poort
staten. I'm surprised no one's forked Elementtree solely to fix this issue.
Anyways, Python's native minidom works as expected, so I'll probably use
that instead, even if the api is slightly less intuitive.
