créer une nouvelle structure et déplacer des éléments avec xslt

Question

J'ai un XML d'entrée plutôt mal formaté qui doit être réorganisé en utilisant xslt 1.0. La hiérarchie doit être modifiée afin que les lignes de détail soient divisées en parties supérieure et inférieure, chacune contenant une partie gauche et une partie droite. J'ai échoué à créer la sortie désirée jusqu'à maintenant. Quelqu'un peut-il m'aider, merci d'avance.

Compte tenu de votre XML exemple, le XSL suivant:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
     <xsl:output method="xml" version="1.0" indent="yes" standalone="no"/> 
     <xsl:strip-space elements="*"/> 

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

     <!-- Match the root node. --> 
     <xsl:template match="document"> 
     <xsl:copy> 
      <!-- Restructure each subset of four Header_Label_Header elements. --> 
      <xsl:for-each select="*[position() mod 4 = 1]"> 
      <xsl:call-template name="subset"> 
       <xsl:with-param name="subset-nodes" select=". | following-sibling::*[position() &lt; 4]"/> 
      </xsl:call-template> 
      </xsl:for-each> 
     </xsl:copy> 
     </xsl:template> 

     <xsl:template name="subset"> 
     <xsl:param name="subset-nodes"/> 
     <!-- Select the first and third elements and give them appropriate upper/lower labels. --> 
     <xsl:for-each select="$subset-nodes[position() mod 2 = 1]"> 
      <xsl:choose> 
      <xsl:when test="position() = 1"> 
       <Header_Label_Upper> 
       <!-- Select this element and the one that follows it. --> 
       <xsl:apply-templates select=". | following-sibling::*[position() &lt; 2]"/> 
       </Header_Label_Upper> 
      </xsl:when> 
      <xsl:otherwise> 
       <Header_Label_Lower> 
       <!-- Select this element and the one that follows it. --> 
       <xsl:apply-templates select=". | following-sibling::*[position() &lt; 2]"/> 
       </Header_Label_Lower> 
      </xsl:otherwise> 
      </xsl:choose> 
     </xsl:for-each> 
     </xsl:template> 

    <!-- Match the Header_Label_Header elements and give them appropriate left/right labels. --> 
    <xsl:template match="*[contains(local-name(), 'Header_Label_Header_')]"> 
    <xsl:choose> 
     <xsl:when test="position() = 1"> 
     <Label_Left> 
      <xsl:apply-templates select="*[contains(local-name(), 'Label_Header_Header_')]"/> 
     </Label_Left> 
     <xsl:apply-templates select="Detail_Line" mode="Left"/> 
     </xsl:when> 
     <xsl:otherwise> 
     <Label_Right> 
      <xsl:apply-templates select="*[contains(local-name(), 'Label_Header_Header_')]"/> 
     </Label_Right> 
     <xsl:apply-templates select="Detail_Line" mode="Right"/> 
     </xsl:otherwise> 
    </xsl:choose> 
    </xsl:template> 

    <xsl:template match="Detail_Line" mode="Left"> 
    <Detail_Line_Left> 
     <xsl:apply-templates/> 
    </Detail_Line_Left> 
    </xsl:template>

     <xsl:apply-templates/> 
    </Detail_Line_Right> 
    </xsl:template> 
</xsl:stylesheet> 

sortie du XML souhaité.

Le modèle pourrait probablement être amélioré car il y a un peu de code dupliqué, mais cela fait l'affaire.
