Here's an example of using XML namespaces with ElementTree:

>>> x = '''\
<channel xmlns:media="http://www.w3.org/TR/html4/">
  <title>Popular  Photography in the last 1 week</title>
  <item>
    <title>foo</title>
    <media:category label="Miscellaneous">photography/misc</media:category>
    <media:content url="http://foo.com/1.jpg" height="375" width="500" medium="image"/>
  </item>
  <item> ... </item>
</channel>
'''
>>> node = ElementTree.fromstring(x)
>>> for elem in node.findall('item/{http://www.w3.org/TR/html4/}category'):
        print elem.text
