Hi again,
Just to clarify, On 8/22/2012 1:29 PM, G. Ken Holman wrote: I just can't figure out where function flexibility is needed ... I cannot see what needs to be tweaked that isn't simply in the groups.xml file. The function served nothing more than a pedagogical use in my solution (which was only a modification of Ken's first solution, thus not a solution at all). It wasn't necessary at all, except for the purposes of (a) showing how a function works, and (b) showing how a function, in a case like this, can expose the logic in a way that makes it a bit easier to read and interpret, as well as to modify in view of new, or changing, or newly understood requirements. In this it's not much different from <xsl:variable name="complicated-xpath"
select="complicated/xpath[if exists(name)
then 'easier to understand']"/>
<xsl:apply-templates select="$complicated-xpath"/>Of course I know it's only easier to read and interpret a function if one knows or can guess how functions work. (In this, a function is like a key.) But that isn't so hard, and learning how to read and interpret XSLT is part of the reason we're here.
