Re: Hello and quick question

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

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,
