Oleg,

Thanks! I got it to work. But I don't quite understand something about xslt.

If I write:

<xsl:param name="node-where-stop" select="an XPath expression that selects my node"/>

it works.

If instead I plug in the same XPath expression in place of $node-where-stop in the count() it doesn't work.

Why? I assume it has something to do with needing a node set. Is there some way I could write the equivalent directly into the count()? I am asking because I am trying to insert this into an Auto-calculation in Stylesheet Designer.

     May be something like
     
     count(
        preceding-sibling::*[
          not(
            following-sibling::*[count(.|$node-where-stop)=1]
          )
        ]
     )
