Sorry, this is a double post, but I had issues with the preformatted code in my replies making it hard to understand.

Chriztian has been a great help, and did all the hard work.

Im still having an issue with appling a class through the with-param on the first group. Ive never tried passing a class this way and was wondering how it works.

Any help would be grateful. Thanks

<xsl:param name="currentPage" />
   
   <!-- This is the number of initial items -->
 <xsl:variable name="offset" select="2" />
    
   <!-- This the number of nodes to group subsequently -->

   <xsl:template match="/">
     
       <!-- Process the MNTP property -->
       <xsl:apply-templates select="$currentPage/homeFeatureBlock" />
       
   </xsl:template>
  
   <!-- Template for the MNTP property -->
  <xsl:template match="homeFeatureBlock">
