RE: xsl grouping problem

I would use

<xsl:for-each-group group-adjacent="self::line or self::line_first or
self::line_last">
  <xsl:choose>
  <xsl:when test="current-grouping-key()">
    <stanza><xsl:copy-of select="current-group()"/></stanza>
  </xsl:when>
  <xsl:otherwise>
    <xsl:copy-of select="current-group()"/>
  </
</
