映射旧ID的第二个文档

the second document mapping the old ids to new ones as in

第二份文件

Second Document

<catalog>
  <ids>
    <package>A</package>
    <id>1</id>
    <newId>A-1001</newId>
  </ids>
  <ids>
    <package>A</package>
    <id>2</id>
    <newId>A-1002</newId>
  </ids>
  <ids>
    <package>A</package>
    <id>3</id>
    <newId>A-1003</newId>
  </ids>
  <ids>
    <package>A</package>
    <id>4</id>
    <newId>A-1004</newId>
  </ids>
  <ids>
    <package>B</package>
    <id>1</id>
    <newId>B-1001</newId>
  </ids>
  <ids>
    <package>B</package>
    <id>2</id>
    <newId>B-1002</newId>
  </ids>
  <ids>
    <package>B</package>
    <id>3</id>
    <newId>B-1003</newId>
  </ids>
  <ids>
    <package>B</package>
    <id>4</id>
    <newId>B-1005</newId>
  </ids>
<ids>
    <package>C</package>
    <id>1</id>
    <newId>C-1005</newId>
  </ids>
<ids>
    <package>D</package>
    <id>2</id>
    <newId>D-1005</newId>
  </ids>
</catalog>

作为输出你只想复制第一个输入但是替换id值然后下面的样式表显示

and as the output you simply want to copy the first input but replace the id values then the following stylesheet shows

<xsl:stylesheet
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  version="1.0">
  
  <xsl:param name="id-url" select="'idmap.xml'"/>
  <xsl:variable name="id-doc" select="document($id-url)"/>
  
  <xsl:key name="k1" match="catalog/ids" use="concat(package, '|', id)"/>
  
  <xsl:template match="@* | node()">
    <xsl:copy>
      <xsl:apply-templates select="@* | node()"/>
    </xsl:copy>
  </xsl:template>
  
  <xsl:template match="cd/id">
    <xsl:copy>
      <xsl:variable name="this" select="."/>
      <xsl:for-each select="$id-doc">
        <xsl:value-of select="key('k1', concat($this/parent::cd/package, '|', $this))/newId"/>
      </xsl:for-each>
    </xsl:copy>
  </xsl:template>
  
</xsl:stylesheet>
