Right. The parsing succeeds but no 'servlet' elements are found and the
loop simply has no effect. I may be missing some technical detail, but I
think the 'servlet' elements in the document are in the default
namespace (because one was declared) while your .findall and .find calls
are looking for a 'servlet' element that is in no namespace at all. I
seem to remember that there is such a distinction in XML.
