And, if you install lxml, then you will be able to use XPath, which
is more powerful that the findtext() in ElementTree.

Stefan did not tell you about that because he is a developer who
has helped give us lxml, and perhaps he is a bit modest.

There is a bit to learn in order to use the XPath capability in
lxml.  But, if you are doing any amount of XML processing in
Python, it's likely to be worth it.

You can learn about lxml here: http://codespeak.net/lxml/
