Re: [xsl] counting with position()

["Imsieke, Gerrit, le-tex" <gerrit.imsieke@xxxxxxxxx>]

for-each-group is the answer to almost anything (next to 42, of course).

<xsl:stylesheet

  <xsl:template match="*[starts-with(name(), 'level')]">
    <xsl:variable name="level-name" select="name()" />
    <xsl:for-each-group select="*" group-starting-with="item">
      <xsl:choose>

        <xsl:otherwise>
