Re: Problem with xsl:template using XSLT 1.0

Hi Gareth,
   I agree to Scott's observations.

Saying in slightly different words ...

You need to swap the things used in 'select' (of xsl:apply-templates
construct), and what used in 'match' (of xsl:template construct).

<xsl:apply-templates select=" ... selects a node list (or 'set') and
applies a template rule to each node in this list (the template rule
'match' pattern matches the nodes in the list).
