RE: [xsl] Sorting a NodeSet Contained Within a Variable

[Bryan Tulloch <b dot tulloch at solicitec dot com>]

Oliver,

Thanks for your guidance, but this isn't working 100% for me.
I can sort the node-set if it is comprised purely of nodes from my xml
source tree, but not if it consists entirely of the results of a series of
calculations (using count()) done on nodes from the source tree. In other
words, I want to put those results into a nodeset and sort them.

Hi Bryan,

Well, you can't sort a node-set because sets are unordered. ;-)
What you can do is to process the nodes of a set in a specific order.

This isn't different from any other expression that evaluates to a node-set.

Just do either

<xsl:apply-templates select="$set">
   <xsl:sort .... />
</xsl:apply-templates>

or 

<xsl:for-each select="$set">
   <xsl:sort .... />
   ....
</xsl:for-each>

Hope that helps,
Oliver
