RE: [xsl] problem creating containment during XHTML->XML

["Michael Kay" <mhk@xxxxxxxxx>]

Try a search for "XSLT positional grouping" (this is a classic problem).

In XSLT 2.0 this is child's play:

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

In 1.0 it's quite hard. In the template that matches <heading> you've
got to process all the following siblings up to the next heading. One
way of selecting these is

following-sibling::*[generate-id(preceding-sibling::heading) =
generate-id(current())]
