RE: [xsl] xslt 2, grouping and more on indexing.

I think we've had a very similar problem to this before.

David Carlisle suggested first converting the markup to textual delimiters,
then doing the regex processing, then converting the delimiters back to
markup.

I suggested processing each text node independently to add markup.

In this situation I think the latter approach works better: instead of

<xsl:copy-of select="dp:sep(text()[1])"/>

do an apply-templates (perhaps in a special mode) that does a recursive
descent of the entry subtree, applying regex processing to each text node
that you find.
