使用XSLT合并两个diff XMLS（1.0）

Question

我是XSLT的新手，我需要帮助将两个不同的XML文档合并为一个。

XML1.xml

<customers> 
    <customer> 
     <Person name="Ram" Id="101"/> 
     <address>flat 4</address> 
    </customer> 
    <customer> 
     <Person name="Raghav" Id="102"/> 
     <address>flat 9</address> 
    </customer> 
</customers> 

XML2.xml

<Products> 
    <Product> 
     <name>Onida Tv</name> 
     <consumer>Ram</consumer> 
    </Product> 
    <Product> 
     <name>washing machine</name> 
     <consumer>Ram</consumer> 
    </Product> 
    <Product> 
     <name>Water purifier</name> 
     <consumer>Raghav</consumer> 
    </Product> 
    <Product> 
     <name>iPhone</name> 
     <consumer>Raghav</consumer> 
    </Products> 
</Products> 

希望的XML输出：

<customers> 
    <customer> 
     <Person name="Ram" Id="101"/> 
     <address>flat 4</address> 
     <products> 
      <name>washing machine</name> 
      <name>Onida TV</name> 
     </products> 
    </customer> 
    <customer> 
     <Person name="Raghav" Id="102"/> 
     <address>flat 9</address> 
     <products> 
      <name>iPhone</name> 
      <name>Water purifier</name> 
     </products> 
    </customer> 
</customers> 

第二XML将被认为是在该上下文中外部。我需要为每个客户添加相应的产品。我怎样才能做到这一点？

试试这样说：

XSLT 1.0

<?xml version="1.0" encoding="UTF-8"?> 
<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:variable name="lookup-document" select="document('XML2.xml')" /> 
<xsl:key name="product-by-consumer" match="Product" use="consumer" /> 

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

<xsl:template match="customer"> 
    <xsl:copy> 
     <xsl:apply-templates select="@*|node()"/> 
     <xsl:variable name="name" select="Person/@name" /> 
     <products> 
      <!-- switch context to the other document in order to use key --> 
      <xsl:for-each select="$lookup-document"> 
       <xsl:copy-of select="key('product-by-consumer', $name)/name"/> 
      </xsl:for-each> 
     </products> 
    </xsl:copy> 
</xsl:template> 

</xsl:stylesheet> 

注意，这个假设客户名称是唯一的。
