ElementTree: namespace declaration in each element?

[cyberco]

The (excellent) ElementLibrary ads namespaces to each element when
writing the tree back to a file.
Say I do:

tree = ET.parse('playlist.xml')
<snip: adding/removing elements>
tree.write(outFile)

with the following XML:

=============
<playlist version="1" xmlns="http://xspf.org/ns/0/">
<trackList>
<track>
<title>Kick off!</title>
</track>
</trackList>
</playlist>
=============

Writing the tree out after adding/removing elements results in:

=============
<ns0laylist version="1" xmlns:ns0="http://xspf.org/ns/0/">
<ns0:trackList>
<ns0:track
<ns0:title>Kick off!</ns0:title>
</ns0:track>
</ns0:trackList>
</ns0laylist>

=============

Unfortunately the client that needs to consume this XML can't handle
the 'ns0:' part of each tag. Is there a way to output XML similar to
the input?

the standard serializer in 1.2 doesn't support default namespaces, so
the quickest way to do this is to loop over all tags (use getiterator),
strip off the "{http://xspf.org/ns/0/}" prefix, add an xmlns attribute
to the root (if necessary), and write it out.

hehehe...I figured it was. Wonder 'who' it was...

OK, that's what I was already doing. Thanks.
Will the standard serializer in 1.3 support default namespaces?

that's the plan. I've been working on a more modular XML writer, which
will make it easier to tweak the output in various ways, without having
to write everything from scratch.
