RE: [xsl] problem with creating structure

["Michael Kay" <mike@xxxxxxxxxxxx>]

There is a construct in XSLT 2.0 explicitly designed for problems like this:

<xsl:for-each-group group-starting-with="h2">

It can be done in XSLT 1.0, using recursion, but requires more effort. So
the first thing to establish is, are you using XSLT 2.0 or 1.0?
