我有这个样式表：

<?xml version="1.0" encoding="ascii"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" exclude-result-prefixes="xsl">
    <xsl:output omit-xml-declaration="yes" method="xml" encoding="UTF-8"/>
    <!--remember the location of the additional assessment information-->
    <xsl:variable name="additional" select="/*/AdditionalAssessment"/>
    <xsl:template match="ApplicationData">
        <!--preserve original data-->
        <xsl:copy-of select="."/>
        <!--now make duplicate-->
        <ApplicationData>
            <!--preserve data attributes-->
            <xsl:copy-of select="@*"/>
            <!--override with additional attributes-->
            <xsl:copy-of select="$additional/@*"/>
            <!--process children looking for modifications to attributes-->
            <xsl:apply-templates select="node()" mode="overrideAttributes"/>
        </ApplicationData>
    </xsl:template>
    <!--copy the element and override attributes form the additional assessment-->
    <xsl:template match="*" mode="overrideAttributes">
        <xsl:copy>
            <!--preserve data attributes-->
            <xsl:copy-of select="@*"/>
            <!--override with additional attributes-->
            <xsl:copy-of select="$additional/*[name(.)=name(current())]/@*"/>
            <!--manipulate the descendants-->
            <xsl:apply-templates mode="overrideAttributes"/>
        </xsl:copy>
    </xsl:template>
    <!--remove the original additional assessment-->
    <xsl:template match="AdditionalAssessment"/>
    <xsl:template match="@*|node()">
        <!--identity for all other nodes-->
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="/ExternalAssessmentRequest">
        <xsl:element name="ApplicationDataBatch">
            <xsl:apply-templates select="@*|node()"/>
        </xsl:element>
    </xsl:template>
</xsl:stylesheet>

产生以下输出：

<ApplicationDataBatch>
    <ApplicationData Lender="TEST">

一切都是应有的，只是缺少一件事。我需要为每个 AdditionalAssessment 节点创建一个 ApplicationData 节点。当前样式表只创建一个而不是 5（+1 原始应用程序数据）。样式表需要为每个 AdditionalAssessment 节点创建 ApplicationData 节点，只需更改每个 Additional Assessment 中指定的元素。

此 XSLT 样式表似乎可以满足您的要求：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" exclude-result-prefixes="xsl">
  <xsl:output omit-xml-declaration="yes" method="xml" encoding="UTF-8"/>

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

  <!-- When we get to AdditionalAssessment elements, match the ApplicationData element again in override-attributes
       mode, passing through the AdditionalAssessment element so we can copy things from it. -->
  <xsl:template match="AdditionalAssessment">
    <xsl:apply-templates select="../ApplicationData" mode="override-attributes">
      <xsl:with-param name="additional" select="."/>
    </xsl:apply-templates>
  </xsl:template>

  <!-- Copying out elements and modifying their attributes according to the 'additional' element we pass in as a
       parameter. -->
  <xsl:template match="node()|@*" mode="override-attributes">
    <xsl:param name="additional" />
    <xsl:copy>
      <!-- Preserve data attributes. -->
      <xsl:copy-of select="@*"/>

      <!--Override with additional attributes. -->
      <xsl:copy-of select="$additional/*[name(.)=name(current())]/@*"/>

      <!-- Override the lender if this is the ApplicationData element. A bit annoying to have to do this, but I couldn't 
           get it to work in a nicer way. -->
      <xsl:if test="self::ApplicationData">
        <xsl:copy-of select="$additional/@Lender"/>
      </xsl:if>

      <!-- Manipulate the descendants, excluding the attributes because we've already copied/overridden them. -->
      <xsl:apply-templates select="node()" mode="override-attributes">
        <xsl:with-param name="additional" select="$additional"/>
      </xsl:apply-templates>
    </xsl:copy>
  </xsl:template>

</xsl:stylesheet>

假设原始文档只有一个 ApplicationData 元素是否安全？如果是这样，那么这应该可以解决问题：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
                exclude-result-prefixes="xsl">
  <xsl:output omit-xml-declaration="yes" method="xml" encoding="UTF-8"/>

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

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

  <xsl:template match="AdditionalAssessment">
    <xsl:apply-templates select ="../ApplicationData" mode="overrideAttributes">
      <xsl:with-param name="additional" select="." />
    </xsl:apply-templates>
  </xsl:template>

  <!--copy the element and override attributes form the additional assessment-->
  <xsl:template match="*" mode="overrideAttributes">
    <xsl:param name="additional" />

    <xsl:variable name="currentIsAD" select="self::ApplicationData" />

    <xsl:copy>
      <!--preserve data attributes-->
      <xsl:copy-of select="@*"/>
      <!--override with additional attributes-->
      <xsl:copy-of select="$additional[$currentIsAD]/@*"/>

      <xsl:copy-of 
          select="$additional[not($currentIsAD)]/*[name(.)=name(current())]/@*"/>
      <!--manipulate the descendants-->
      <xsl:apply-templates mode="overrideAttributes">
        <xsl:with-param name="additional" select="$additional" />
      </xsl:apply-templates>
    </xsl:copy>
  </xsl:template>

</xsl:stylesheet>
