xml を変換する xslt スタイル シートを作成しようとしています。私はミューエンチャン法を研究しましたが、それがどのように機能するかについてはよく知りません. すべての ManifestNo に任意の数の SequenceNo を含めることができるため、問題が発生しています。ソース xml のフラットな注文を、ネストされたストップの詳細を持つ宛先 xml の注文にグループ化しようとしています。

<Orders>
  <Order>
    <ManifestNo>283749</ManifestNo>
    <Warehouse>35</Warehouse>
    <SequenceNo>1</SequenceNo>
    <CustomerOrderNo>3524771-01</CustomerOrderNo>
    <Weight>180</Weight>
  </Order>
  <Order>
    <ManifestNo>283749</ManifestNo>
    <Warehouse>35</Warehouse>
    <SequenceNo>1</SequenceNo>
    <CustomerOrderNo>3524771-02</CustomerOrderNo>
    <Weight>250</Weight>
  </Order>
  <Order>
    <ManifestNo>283749</ManifestNo>
    <Warehouse>35</Warehouse>
    <SequenceNo>2</SequenceNo>

I.このXSLT1.0変換：

    <xsl:stylesheet version="1.0"

     <xsl:output omit-xml-declaration="yes" indent="yes"/>

提供されたXMLドキュメントに適用した場合：

<Orders>

    <ManifestNo>283749</ManifestNo>
    <Warehouse>35</Warehouse>
    <SequenceNo>1</SequenceNo>
    <CustomerOrderNo>3524771-01</CustomerOrderNo>
    <Weight>180</Weight>
  </Order>
  <Order>
    <ManifestNo>283749</ManifestNo>
    <Warehouse>35</Warehouse>
    <SequenceNo>1</SequenceNo>
    <CustomerOrderNo>3524771-02</CustomerOrderNo>
    <Weight>250</Weight>

    <CustomerOrderNo>3524888-01</CustomerOrderNo>
    <Weight>95</Weight>
  </Order>

II。XSLT 2.0ソリューション：

<xsl:stylesheet version="2.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:key name="kSeqByOrderNo" match="SequenceNo"
      use="../ManifestNo"/>

 <xsl:template match="/*">
   <Orders>
     <xsl:for-each-group select="Order" group-by="ManifestNo">
      <Order>
        <xsl:copy-of select="ManifestNo|Warehouse"/>

        <xsl:for-each-group select="key('kSeqByOrderNo', ManifestNo)"
         group-by=".">
         <xsl:copy-of select="."/>
         <Stop>
          <xsl:apply-templates select="current-group()"/>
         </Stop>
        </xsl:for-each-group>
      </Order>
     </xsl:for-each-group>
   </Orders>
 </xsl:template>

 <xsl:template match="SequenceNo">
   <Freight>
     <xsl:copy-of select="../CustomerOrderNo|../Weight"/>
   </Freight>
 </xsl:template>
</xsl:stylesheet>
