使用XSLT根据节点值合并两个不同的XML文件

Question

I am trying to merge two XML files using XSLT. I need to match the tradeId node value which must present in both files, and just copy all the content to file1 .

Any help would be welcome. All similar examples are based on attributes and same XML which does not work for me.

File1.xml

<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">

  <S:Body>

    <trade>
      <tradeId>1</tradeId>
      <createdBy>1</createdBy>
      <createdOnDate>2</createdOnDate>

        <indicator>3</indicator>
        <updateBy>4</updateBy>

Answer 1

If you apply this stylesheet to file1.xml it will explicitly include the corresponding information from file2.xml using the document function. There is no need to declare the namespace S in the stylesheet as the relevant elements have no namespace. I hope this helps.

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

  <xsl:strip-space elements="*"/>
  <xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>

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

  <xsl:template match="trade">
    <xsl:copy>
      <xsl:apply-templates/>
      <xsl:copy-of select="document('file2.xml')//financialexpectation[tradeId=current()/tradeId]"/>
    </xsl:copy>
  </xsl:template>

</xsl:stylesheet>

output

<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
   <S:Body>
      <trade>
