Hi,

Now I see what was wrong with my reasoning. I was misunderstanding the
XML structure. Somehow, I thought that the only topic at the same
level as the key was the one we wanted to search. Looking more closely
I realized that key is at the same level as all other topic nodes in
the document.

Thanks,

Jesus.
