I'm setting up a recursive template in order to count the amount of
unique records at the end for tabulation.
This is usually done using a grouping idiom (see jeni's pages for xslt1
or for-each-group in xslt2)
I'm wondering if I can use xsl:sort to get the names in order, then
have the template check to see if the following-sibling matches.
xsl:sort changes the order in which teh results of processing nodes are
added to the result tree, it doesn't change the input tree, so it does
not change the preceding-sibling axis of the nodes.
Would xsl:sort only sort the first record (doing nothing)?
yes.
<xsl:for-each select="Record[1]">
<xsl:apply-templates select="." />
</xsl:for-each>
That is equivalent to
<xsl:apply-templates select="Record[1]"/>
