我想加入两个 xml 文件，如下图所示。但是我的问题是，如果您有一个 ID 可以加入，您将如何做到这一点。我想加入关于 POSITION 而不是 id 的加入。您将如何对以下文件执行此操作？

文件 1：

<?xml version="1.0" encoding="ISO-8859-1"?>
<catalog>
  <data>
    <title>Title1</title>
    <description>Description1</description>
  </data>

  <data>
    <title>Title2</title>
    <description>Description2</description>
  </data>
</catalog>

文件 2：

<?xml version="1.0" encoding="ISO-8859-1"?>
<catalog>
  <data>
    <author>Author1</author>
    <date>12/34/5678</date>
  </data>

  <data>
    <author>Author2</author>
    <date>87/65/4321</date>
  </data>
</catalog>

输出：

<?xml version="1.0" encoding="ISO-8859-1"?>
<catalog>
  <data>
    <title>Title1</title>
    <description>Description1</description>
    <author>Author1</author>
    <date>12/34/5678</date>
  </data>

  <data>
    <title>Title2</title>
    <description>Description2</description>
    <author>Author2</author>
    <date>87/65/4321</date>
  </data>
</catalog>

如果您有一个ID使用下面 XSLT 的公共字段，我知道该怎么做，但是您如何加入 POSITION？

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:transform version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml" version="1.0" encoding="ISO-8859-1" indent="yes" />
  <xsl:variable name="with" select="'File2.xml'" />

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

  <xsl:template match="scene">
    <xsl:copy>
      <xsl:apply-templates select="@*|node()" />
      <xsl:variable name="info" select="document($with)/catalog/data[id=current()/id]/." />
      <xsl:for-each select="$info/*">
        <xsl:if test="name()!='myid'">
          <xsl:copy-of select="." />
        </xsl:if>
      </xsl:for-each>
    </xsl:copy>
  </xsl:template>
</xsl:transform>

尝试

<xsl:strip-space elements="*"/>
<xsl:output indent="yes"/>

<xsl:param name="url2" select="'input2.xml'"/>
<xsl:variable name="data2" select="document($url2)/catalog/data"/>

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

<xsl:template match="data">
  <xsl:variable name="pos" select="position()"/>
  <xsl:copy>
    <xsl:apply-templates select="@* | * | $data2[$pos]/*"/>
  </xsl:copy>
</xsl:template>

                         Also, counting preceeding-siblings that are data 
                         elements, not just any element. -->
