I was talking about the eq operator, but you could use compare() if you
prefer. Or even "=". Something like
id('010003-031') eq id('010003-057')
if those are two ads you believe to be duplicates.
Oh - I've just noticed your ID values aren't valid ID values - an ID can't
start with a digit. So change that to
//ad[@xml:id='010003-031'] eq //ad[@xml:id='010003-057']

You're comparing whether <ad> elements are duplicates, not whether their
<head> elements are duplicates. Is that perhaps the source of your

There could be all kind of things, for example a capital Latin A in one
versus a capital Cyrillic A in the other would not readily show up when
viewed on the screen. OK, perhaps that's unlikely - but I've no way of
knowing that. That's why I asked you to run the test.
