I may have answered my own question by experimentation.
This xsl fragment seems to work:
string(/ROOT/Client/Contacts/Contact[isReferrer='0']/ContactFirstName)
By only returning a string representation of the first node in this set.
Is this the "right" way to accomplish this or is there a better/more
preferred way?
Thanks again,
Corey Snow

Subject: [xsl] Hello and quick question
Hi all- good to be back on the list; I got bounced from my
old job and haven't been in a position to collect a lot of
email in that time.
I have a quick question for you XSLT-guru types: How can I
obtain the first node of a set of nodes that meets a given
set of criteria? In my case, I have an XML document that
contains zero or more nodes in a particular element, like so:
<ROOT>
<Client>
... Various elements here ...
<Contacts>
<Contact ContactId='5'>
... Contact information ...
<IsReferrer>1</IsReferrer>
</Contact>
<Contact ContactId='10'>
... Contact information ...
<IsReferrer>0</IsReferrer>
</Contact>
<Contact ContactId='25'>
... Contact information ...
<IsReferrer>1</IsReferrer>
</Contact>
</Client>
</ROOT>
I have no real control over the order of these elements, and
what I need to be able to do is obtain the first Contact
element which has zero
('0') in the IsReferrer element. Actually, I need to get the
value of a child element (ContactFirstName) of this element.
I can do something like:
/ROOT/Client/Contacts/Contact[IsReferrer='0']/ContactFirstName
but that returns a node-set, not a single node. I assume I
need to do something with the position() function, but I'm
not sure how to go about it.
Thanks in advance for any assistance,
