Well, the Cookbook didn't help with this problem, or at least not that I saw.
So, my data (in part) is like this..
<xtvd>
...
<programs>
<program id(_at_)="...">
<title> ... </title>
<subtitle> ... </title>
<description ... </title>
...
</program>
<program>
...
</program>
...
</programs>
...
</xtvd>
(Yes, it's the ever-popular DataDirect TV listings from Tribune Media
Services... I'm working with the data in its "native" xtvd structure,
rather than doing the very long-winded transform to the more popular
XMLTV structure.)
I want to find <program> elements whose <title> or <subtitle> or
<description> might contain the string I've stowed in the variable
$target. Something simple like
<xsl:if test="matches(normalize-space(//tv:program),$target)">
fails, since the first argument wants to be a node, not a sequence. I
can't think of any better solution than looping through all the
programs, looking inside, but with several thousand programs and
several keywords to process ... I hope someone here can see a better
way!
Would it be possible to do this with a key? For example,
<xsl:key name="$target" match="(//title[matches(.,$target)]) or
(//subtitle[matches(.,$target)]) or
(//description[matches(.,$target)])" use="../@id" />
Gee, that looks promising. Must be something wrong with it. I'll try
it. Meanwhile, happy to hear other advice!
