Thanks for the suggestion David. But I can't get it to work. Here's my test code:

I get no output. But when I use the non-key lookup (commented out) I get "A", as expected. This is with libxslt's xsltproc:
Does it work correctly on other processors?

All that is stopping me is that XSLT doesn't - as far as I know - allow for keys to be used on exsl:node-set()s,
keys, once set up, automatically apply, separately, to any document that is used and so if your exsl:node-set() returns a node set consisting of a root node / which it will if it is given a result tree fragment coming from xsl:variable, then your keys will apply to that.
Thanks for the suggestion David. But I can't get it to work. Here's my test code:
<xsl:transform version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:exsl="http://exslt.org/common" extension-element-prefixes="exsl">
<xsl:key name="k" match="a" use="@x"/>
<xsl:template match="/"> <xsl:variable name="v"> <n> <a x="1" y="A"/> <a x="2" y="B"/> </n> </xsl:variable> <xsl:apply-templates select="exsl:node-set($v)/*"/> </xsl:template>
<xsl:template match="n"> <!-- <xsl:apply-templates select="a[@x='1']"/> --> <xsl:apply-templates select="key('k','1')"/> </xsl:template>
<xsl:template match="a"> <xsl:value-of select="@y"/> </xsl:template>
</xsl:transform>
I get no output. But when I use the non-key lookup (commented out) I get "A", as expected. This is with libxslt's xsltproc:
$ xsltproc --version Using libxml 20610, libxslt 10105 and libexslt 804
Does it work correctly on other processors?
