[WG] CSML default namespace handling bug

[mggr]

In our current CSML, we have the namespaces explicit (ie. each element is specified with a namespace, with no default namespace). The xml handling code in models/xmlHandler2.py assumes that CSML is the default namespace in one part and blows up (since we don't have a default namespace). The rest of the code doesn't make this assumption, so it's probably just a minor bug.

This can be fixed by the following patch:

I'm going to completely refactor this when we have the new element tree which handles namespaces more elegantly ...

Issue still exists (and still needs patching for PML records) - just got hit by ~1000 72kb server error emails caused by googlebot ;)

The code has moved into the ndgUtils egg but hasn't changed. The egg makes it more messy to do a local patch, it's not an obvious problem when it breaks and it's been a while, so I'm committing the fix above to subversion. Hope that's ok.

Except I'm not :/

Looks like I'm in the wrong usergroup now (in cvsusers but not in ndgsvn group). On the other hand, my user id should probably be deleted anyway ;)

Anyone else willing to do this for me?
