Failure under python 2.7

I came to this error through pelican but I can reproduce it by the test suite:

 $ nosetests

I note that the offending function has been removed from django: https://github.com/django/django/blob/master/django/utils/xmlutils.py

Alas, I'm really short on spare time these days -- if you could provide a PR with a fix, that would be much appreciated. Thanks.
