Hi Bruce,

In XSLT 1.0 the only way to do this would be by using a stylesheet to

Ugh.
Maybe Mike or Jeni or someone can suggest an easier way to do this in
XSLT 2.0.
Maybe use a key?
Nope. A key can be used to retrieve nodes dynamically, but it's a way
around slow and tortuous XPaths (that is, an optimization that XPath offers
itself), not a way of manipulating XPath.
I'm confused (again!). I'm basically trying to rework some of my code, in
part based around Geert's suggestions, but I can't really see how to do
what I'm wanting to do (which is to be able to work on content from
external files). It seems, for example, that I cannot use a key on
content I want to access via the doc function.
You mean the document() function, I take it. But no, you're not going to be
able to use key() to retrieve nodes dispersed throughout an arbitrary
number of external documents. It works on one document at a time.
If you know all your nodes of interest are in a single document, you can
change context to that document and use key() therein:
<xsl:variable name="bibrecord" select="document(concat('bib-data/',
$bibkey, '.mods'))" />
<xsl:key name="biblio" match="mods:mods" use="@ID" />
<xsl:template match ...>
<xsl:variable name="key-value" select="[your key value]"/>
<!-- ... now changing context to the bibrecord document -->
<xsl:for-each select="$bibrecord">
<!-- ... now changing context to the key-retrieved element
inside the bibrecord doc -->
<xsl:for-each select="key('biblio', $key-value">
... do your thing ...
</xsl:for-each>
</xsl:for-each>
</xsl:template>
But I'm not sure that's quite enough to give you what you need. Maybe.
Cheers,
Wendell
