 My first post here and I want to start by saying how much I appreciate the big FAQ, the Jeni site, etc. It has all helped me tremendously. I can't find an answer to this one, though, so here goes... My XML doc has this basic structure:
<a>
<b>
<c>
<!-- This is the section of interest -->
</c>
</b>
</a>The <c> element can contain any combination of elements <d> through <z>. Elements <y> and <z> have special uses. I want to create a global variable that contains the result tree fragment contained within element <c>, with the following restrictions: I only want to include the first <y> element that is contained within <c>, no matter where it occurs. There may be no <y> elements present. I want to exclude all <z> elements that are contained within <c>, no matter where they occur. Again, there may be none present. Later on in my stylesheet, I use exslt:node-set() on the variable and process the node set. For instance, given this source:
<a><b><c>
<d>
<z>
<g />
</d>
<q>
<r>
<y />
<z />
</r>
<y />
<q>
<y>
</c></b></a>I want the selection to contain this:
<a><b><c>
<d>
<g />
</d>
<q>
<r>
<y />
</r>
<q>
</c></b></a>(<z> elements are gone, only the first <y> element remains.) I have tried many variations on the select portion of the variable definition. I can filter the immediate children of <c>, OR the second level children, etc., but I can't seem to come up with anything that handles <y> and <z> appearing at any depth in the descendant tree. I'm prepared to be humiliated by some obvious solution... Can anyone please help? Thanks, Rush
