It might be because key() selects only nodes in the document containing
the context node, which you've made into the stylesheet itself with your
xsl:for-each. So there are no nodes matching /items/item to be selected.
That's the conclusion I reached too.
I'm guessing that you are stuck using XSLT 1.0, because you don't need to
do the document('') shenanigans in XSLT 2.0, so the latter's
three-argument version of key() likely won't help.
Yes, that's correct - XSLT 1.0
> You could wrap the
above-quoted xsl:apply-templates in another xsl:for-each that puts the
context node back to the document that you want to process:
<xsl:variable name="item-document" select="/"/>
<xsl:for-each select="document('')//me:month">
...
<xsl:for-each select="$item-document">
<xsl:apply-templates select="key('by-month', $month)">
...
</xsl:for-each>
</xsl:for-each>
but it's starting to look a tad messy.
Aha, that was just what I was looking for - it didn't click that doing a
for-each on the root node would only cause one "iteration". At this
point I'm only using it in one place, so I can live with the messiness
(it's still cleaner than copying and pasting the same block 12 times!)
Thanks for your help!
Cheers,
Adam.
