xsl:for-each-group question

Unsing xsl 2.0

 

The below xsl changes the below xml with a list of flat <P/> nodes into
groups based on values in subnodes of <p/>

The result achived with the xsl below is what I want.

 

But what I cannot figure out is:

 

What values must the "select" argument and/or the "group-starting-with"
arguments have in my example

so that the resulting current-group() nodes are <p/> nodes (i.e. the parent
node) instead of <rStyle/> nodes.

 

I cannot achieve the wanted grouping with the resulting current-group()
nodes being <p/> nodes.

I can only achieve the wanted grouping with the resulting current-group()
nodes being <rStyle/> nodes.

 

Thank you for any help.

Kind regards

Markus
