Chris,

Well, it's true I made a couple of assumptions (based on your description) about how your input data looks. To wit: that the values you are checking are all element children of the nodes you are testing (and not, for example, attributes).

Could we see a snippet of input data to confirm whether this is the case?

Yes, it's true preceding-sibling::* returns all preceding siblings. But the predicate expression filters this list. The trick is to get the filter right.

Cheers,
Wendell

Thanks for the try.

What you said makes complete sense and it looked to me like it should
work, but now I have the opposite problem... It's including everything.
:p

Preceding-sibling::* means ALL preceding siblings, correct?  If not,
that may be my problem, because the XML is not sorted/grouped in an
orderly fashion *grimace*.

Chris
