[xsl] Relationships in for-each statement

2006-09-07 14:02:07
Last one for the week, I promise. :-)

Here's the data structure

<productionCrew>
   <crew @program= "">
       <member>
           <role> ... </role>
           <givenname> ... </givenname>
           <surname> ... </surname>
           ...
        </member>
   </crew>
   <crew>
   ...
   </crew>
</productionCrew>

I have my test to see if it's finding my target person's name (and
that person is acting) anyplace...

<xsl:if test="//member[(role='Actor') or (role='Guest Star') or
(role='Host')][concat(tv:givenname, ' ', tv:surname) = $matcher]">

Which works fine. Once I know the person is in the data, I go looking
in detail, and my current solution for that is...

<!-- Loop on every crew listed -->
<xsl:for-each select="//member[(role='Actor') or (role='Guest Star')
or (role='Host')][concat(tv:givenname, ' ', tv:surname) = $matcher]" >
       <!-- Get //crew @program and do stuff -->
        <xsl:variable name="progID" select="../@program" />
        <!-- And stuff -->

... which works. But I have similar loops elsewhere where I can
successfully get those two operations combined into a single for-each.
The simplest one is...

<xsl:for-each select="//program[tv:title = $matcher]/@id">

How would I go about getting to where my for-each would be operating
from the @program of (the assorted met conditions)?

Thanks, again, for your patience.
