Answer 1

Vous avez le droit de regroupement dans l'approche de votre feuille de style mais vous faites à l'intérieur du for-each-group des choses trop compliquées, il suffit d'utiliser

<xsl:template match="contents"> 
    <contents> 
     <xsl:for-each-group select="unnumbered" group-starting-with="unnumbered[@type='PT']"> 
      <unnumbered> 
       <xsl:apply-templates select="@*, node(), current-group() except ."/> 
      </unnumbered> 
     </xsl:for-each-group> 
    </contents> 
</xsl:template>
