Why lxml.find() calls return False..

What happens is that an element evaluates to False if it has no 
children, and True if it does. The presence of text content, attributes 
or a tail does not affect the boolean status; if no elements exist it'll 
still be False.

find() has the behavior to return None if the value cannot be found. You 
can change your tests to something like:

if xmldoc.find('child') is not None:

to check whether you have a child.
