xsl ques - is a value contained in a node of elements?

[chris markiewicz <cm...@commnav.com>]

hello.

a little background...i am passing back workflow objects and a list of
workflow-person associations (for a given person).

example:

<workflow>
<wfid>5</wfid>
...
</workflow>
...

and

<wfperassoc><wfid>5</wfid><perid>100</perid></wfperassoc>
<wfperassoc><wfid>6</wfid><perid>100</perid></wfperassoc>
...

when i get to a workflow (id=5), i want to see if that person (id = 100) is
associated.  is there any function that handles this sort of thing?

thanks
chris
