XSLT - Comptage des nœuds enfants après l'application du groupement muenchian

Question

Pour le code XML d'entrée ci-dessous, je peux grouper tous les éléments <invoice> enfants sous l'élément <shippingBill> approprié en utilisant la méthode muenchian grouping. Cependant, il est nécessaire d'inclure le count du nombre d'éléments <shippingBill> et les éléments <invoice> dans le résultat final XML. Je ne suis pas sûr de savoir comment s'y prendre.

XML d'entrée

<bank> 
    <shippingBills> 
     <shippingBill> 
      <shippingBillNo>5786885</shippingBillNo> 
      <shippingBillDate>10/02/2016</shippingBillDate> 
      <LEODate>11/02/2016</LEODate> 
      <invoice> 
       <invoiceSerialNo>1</invoiceSerialNo> 
       <invoiceNo>183</invoiceNo> 
       <invoiceDate>07/02/2016</invoiceDate> 
      </invoice> 
     </shippingBill> 
     <shippingBill> 
      <shippingBillNo>5786885</shippingBillNo> 
      <shippingBillDate>10/02/2016</shippingBillDate> 
      <LEODate>11/02/2016</LEODate> 
      <invoice> 
       <invoiceSerialNo>2</invoiceSerialNo> 
       <invoiceNo>184</invoiceNo> 
       <invoiceDate>07/02/2016</invoiceDate> 
      </invoice> 
     </shippingBill> 
     <shippingBill>

     </shippingBill> 
    </shippingBills> 
</bank>

XML final de sortie requise

L'élément <checkSum> a été ajoutée, qui a des éléments enfants qui maintiennent le c respective ounts.

<bank> 
    <checkSum> 
     <noOfInvoices>4</noOfInvoices> 
     <noOfShippingBills>2</noOfShippingBills> 
    </checkSum> 
    <shippingBills>

Answer 1

je le ferais de cette façon:

XSLT 1,0

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
    <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes" /> 
    <xsl:strip-space elements="*" /> 
    <xsl:key name="key-bill" match="shippingBill" use="shippingBillNo" /> 

    <!-- identity transform --> 
    <xsl:template match="@*|node()"> 
     <xsl:copy> 
      <xsl:apply-templates select="@*|node()" /> 
     </xsl:copy> 
    </xsl:template> 
    <xsl:template match="shippingBills"> 
     <xsl:variable name="distinct-bills" select="shippingBill[generate-id() = generate-id(key('key-bill', shippingBillNo)[1])]" /> 
     <checkSum> 
      <noOfInvoices> 
       <xsl:value-of select="count(shippingBill/invoice)" /> 
      </noOfInvoices> 
      <noOfShippingBills> 
       <xsl:value-of select="count($distinct-bills)" /> 
      </noOfShippingBills> 
     </checkSum> 
     <xsl:copy> 
      <xsl:apply-templates select="$distinct-bills" mode="group" /> 
     </xsl:copy> 
    </xsl:template> 
    <xsl:template match="shippingBill" mode="group"> 
     <shippingBill> 
      <xsl:apply-templates select="*[not(self::invoice)]" /> 
      <invoices> 
       <xsl:apply-templates select="key('key-bill', shippingBillNo)/invoice" /> 
      </invoices> 
     </shippingBill> 
    </xsl:template> 
</xsl:stylesheet>
