Your two template rules work well. However, I think I have managed to misrepresent the problem--one of the main pitfalls of submitting queries, it seems.

The problem is this: The <story-title> element is the opening element of a "story" (as opposed the <story> element which is courtesy of the xhtml export from InDesign). At any rate, each "story" is composed of multiple elements such as <story>, <page>, and <imggroup>. That is why I am trying to execute a two-level grouping rule. The outer for-each-group should structure the <level1 class="unit"> hierarchy; the inner for-each-group should structure the <level2 class="selection">.

This stylesheet should do:

<xsl:stylesheet
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  version="2.0">

<xsl:output method="xml" indent="yes"/>

<xsl:strip-space elements="*"/>

  <xsl:template match="@* | node()">
    <xsl:copy>
      <xsl:apply-templates select="@* | node()"/>
    </xsl:copy>
  </xsl:template>

<xsl:template match="bodymatter"> <xsl:copy> <xsl:apply-templates select="@*"/> <xsl:for-each-group select="*" group-starting-with="story[cluster_num]"> <level1 class="unit" unitnum="{position()}"> <xsl:for-each-group select="current-group()" group-starting-with="story[story-title]"> <xsl:choose> <xsl:when test="current-group()[1][self::story[story-title]]"> <level2 class="selection"> <xsl:apply-templates select="current-group()"/> </level2> </xsl:when> <xsl:otherwise> <xsl:apply-templates select="current-group()"/> </xsl:otherwise> </xsl:choose> </xsl:for-each-group> </level1> </xsl:for-each-group> </xsl:copy> </xsl:template>

</xsl:stylesheet>
