RE: [xsl] Grouping with contains

["Michael Kay" <mike@xxxxxxxxxxxx>]

It looks to me as if you are partitioning the URLs into two groups. You
don't need Muenchian grouping where the number of groups is fixed and the
grouping keys (in this case a boolean: contains(., 'globalfolder')) are
known statically.

You can just write:

<table>
  <xsl:apply-templates select="R[contains(URL,'globalfolder')]"/>
</table>
<br/>
<table>
  <xsl:apply-templates select="R[not(contains(URL,'globalfolder'))]"/>
</table>
