Ok, works perfect. Thanks!

But I don't really understand the logic:

given I have the node A

<filename>path</filename>

A.firstChild.nodeValue == path

How would the second child of A look like? (ok, None in this case) How would
a XML fragment look like that has a second child?

What would be the nodeValue of A?

for me a child of a node is something like

<filename>
  <child1 />
  <child2 />
</filename>


Thanks,
