如何使用模板格式为此XML创建xslt？

Question

我在创建XSLT的模板匹配方式上一直遇到这个难题。我面临的问题是我正在创建的XSLT输入似乎有一些问题，该问题无法生成适当的转换后的xml。我无法弄清楚实际出了什么问题。

这是我的XML文件代码：-

<?xml version="1.0" encoding="utf-8"?>
<Materials xmlns="D.Manufacturing.Engineering">
  <Changes>
     <Material MaterialNumber="TEST_ID1"> 
       <Plant>Pla1</Plant> 
       <Description>Description 1</Description> 
       <DescV>Description1 in V</DescV> 
       <UnitOfMeasurement>Kg</UnitOfMeasurement> 
       <MaterialGroup>MatGrp 1</MaterialGroup> 
       <MaterialGroupDesc>Kg</MaterialGroupDesc> 
       <TraceablePartIndicator>0</TraceablePartIndicator> 
       <KeyDataGroup>KeyDataGroup1</KeyDataGroup> 
       <Vendor>VendorID</Vendor> 
       <VendorName>VendorName1</VendorName> 
       <PackageQuantity>1</PackageQuantity> 
       <PackageNetWt>1</PackageNetWt> 
       <PackageUOM>nos</PackageUOM>
     </Material> 
    <Material MaterialNumber="TEST_ID2">
      <Plant>Pla2</Plant>
      <Description>Description 2</Description>
      <DescV>Description 2 in V</DescV>
      <UnitOfMeasurement>Kg</UnitOfMeasurement>
      <MaterialGroup>MatGrp 2</MaterialGroup>
      <MaterialGroupDesc>Kg</MaterialGroupDesc>
      <TraceablePartIndicator>0</TraceablePartIndicator>
      <KeyDataGroup>KeyDataGroup1</KeyDataGroup>
      <Vendor>VendorNID1</Vendor>
      <VendorName>VendorName1</VendorName>
      <PackageQuantity>1</PackageQuantity>
      <PackageNetWt>1</PackageNetWt>
      <PackageUOM>nos</PackageUOM>
    </Material>
    <Material MaterialNumber="TEST_ID3">
      <Plant>Pla3</Plant>
      <Description>Description 3</Description>
      <DescV>Description 3 in V</DescV>
      <UnitOfMeasurement>Kg</UnitOfMeasurement>
      <MaterialGroup>MatGrp 3</MaterialGroup>
      <MaterialGroupDesc>Kg</MaterialGroupDesc>
      <TraceablePartIndicator>1</TraceablePartIndicator>
      <KeyDataGroup>KeyDataGroup1</KeyDataGroup>
      <Vendor>VendorNID1</Vendor>
      <VendorName>VendorName1</VendorName>
      <PackageQuantity>1</PackageQuantity>
      <PackageNetWt>1</PackageNetWt>
      <PackageUOM>nos</PackageUOM>
    </Material>
  </Changes>
  <Deletes>
    <DeleteMaterial MaterialNumber="ID10" />
    <DeleteMaterial MaterialNumber="ID20" />
    <DeleteMaterial MaterialNumber="ID30" />
  </Deletes>
</Materials>

这是我的xslt：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output encoding="UTF-8" indent="yes" method="xml" version="1.0"/>
    <xsl:template match="Materials[@xmlns='D.Manufacturing.Engineering']">

        <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:trac="http://mes.com/TrackingCar">
            <soapenv:Header />
            <soapenv:Body>
                <trac:MES_VEHICLE_STATUS_DESCRIPTOR>
                    <xsl:element name="ORDERHEADER">

                        <xsl:apply-templates select="/Materials/Changes/Material"/>
                    </xsl:element>
                </trac:MES_VEHICLE_STATUS_DESCRIPTOR>
            </soapenv:Body>
        </soapenv:Envelope>         
    </xsl:template>


    <xsl:template match="/Materials/Changes/Material">
        <xsl:element name="Material">
            <xsl:element name="MaterialID">
                <xsl:value-of select="@MaterialNumber"/>
            </xsl:element>
            <xsl:element name="Plant">
                <xsl:value-of select="../Plant/text()"/>
            </xsl:element>
            <xsl:element name="Description">
                <xsl:value-of select="../Description/text()"/>
            </xsl:element>
            <xsl:element name="DescV">
                <xsl:value-of select="../DescV/text()"/>
            </xsl:element>
            <xsl:element name="UnitOfMeasurement">
                <xsl:value-of select="../UnitOfMeasurement/text()"/>
            </xsl:element>
            <xsl:element name="MaterialGroup">
                <xsl:value-of select="../MaterialGroup/text()"/>
            </xsl:element>
            <xsl:element name="MaterialGroupDesc">
                <xsl:value-of select="../MaterialGroupDesc/text()"/>
            </xsl:element>
            <xsl:element name="TraceablePartIndicator">
                <xsl:value-of select="../TraceablePartIndicator/text()"/>
            </xsl:element>
            <xsl:element name="KeyDataGroup">
                <xsl:value-of select="../KeyDataGroup/text()"/>
            </xsl:element>
            <xsl:element name="Vendor">
                <xsl:value-of select="../Vendor/text()"/>
            </xsl:element>
            <xsl:element name="VendorName">
                <xsl:value-of select="../VendorName/text()"/>
            </xsl:element>
            <xsl:element name="PackageQuantity">
                <xsl:value-of select="../PackageQuantity/text()"/>
            </xsl:element>
            <xsl:element name="PackageNetWt">
                <xsl:value-of select="../PackageNetWt/text()"/>
            </xsl:element>
            <xsl:element name="PackageUOM">
                <xsl:value-of select="../PackageUOM/text()"/>
            </xsl:element>
        </xsl:element>
    </xsl:template>
</xsl:stylesheet>

我尝试了各种组合，但无法生成适当的xslt来获取转换后的XML。请让我知道问题出在哪里以及如何解决。
