  <xsl:key name="id" match="pageid" use="."/>
  <xsl:template match="docroot">
    <xsl:copy>
      <xsl:for-each select="token/pageid[generate-id(.) = generate-id(key('id', .))]">
        <xsl:sort select="count(key('id', .))" data-type="number" order="descending"/>
        <xsl:copy-of select="."/>
      </xsl:for-each>
    </xsl:copy>
  </xsl:template>
