Subject: RE: [xsl] for-each-group usage
saxon:evaluate() is always going to be expensive. In situations where
you
are using the same expression repeatedly (e.g. to calculate a sort key
or a
grouping key) it's well worth splitting it into its two halves,
saxon:expression and saxon:eval:
<xsl:variable name="sortkey"
select="saxon:expression(../data-set/order-by/@xpath)"/>
then
<xsl:sort select="saxon:eval($sortkey)"/>
