我已经处理了以下 XSLT 文件，它将让我大部分时间到达那里，但我无法弄清楚如何防止 FLODERS 节点的重复。XSLT 看起来像这样：

<?xml version="1.0" encoding="utf-8"?>

        </xsl:when>
    </xsl:choose>
</xsl:template>
</xsl:stylesheet>

我从转换中获得的输出具有嵌套正确的第一个块，但我无法弄清楚如何防止转换查看它已经处理的节点。有很多重复，这是我试图消除的。一个多星期以来，我一直在尝试解决这个问题，并且真的可以使用一些帮助。在此先感谢所有 XML/XSLT 专家。

这个模板应该可以解决您的问题。

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:msxsl="urn:schemas-microsoft-com:xslt"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  version="1.0"
  exclude-result-prefixes="msxsl">
  <xsl:output method="xml" indent="yes"/>

  <!--
    Initial template.
    -->
  <xsl:template match="/TmData">
    <xsl:copy>
      <xsl:copy-of select="@*"/>
      <xsl:call-template name="folders">
        <xsl:with-param name="depth" select="0"/>
        <xsl:with-param name="risks" select="DocumentElement/Risks"/>
      </xsl:call-template>
    </xsl:copy>
  </xsl:template>

  <!--
    This template is applied to <Risks/>, once the folder for the risk
    has been built.
    -->
  <xsl:template match="Risks" mode="folder-content">
    <Risk>
      <xsl:copy-of select="@*|element()[not(starts-with(local-name(), '_') or contains(local-name(), 'FOLDER'))]"/>
    </Risk>
  </xsl:template>

  <!--
    Called to build out the folders at a given depth.
    params:
      depth: the current folder depth.
      risks: the risks that are in this folder.

  <xsl:template name="folders">
    <xsl:param name="depth"/>
    <xsl:param name="risks"/>
    <FOLDERS>
      <xsl:call-template name="folder">

        <xsl:with-param name="risks" select="$risks"/>
      </xsl:call-template>
    </FOLDERS>
  </xsl:template>

  <!--

    in the risks parameter.  It then creates the nested folders for that risk, by
    calling the folders template with the risks that are in the folder.  Finally,
    the template creates more folders at the same depth, by calling itself with
    the risks that were not in this folder.

    params:
      depth: the current folder depth.
      risks: the risks that are in this folder.

  <xsl:template name="folder">

    <xsl:if test="$risks">
      <xsl:variable name="element-name">
        <xsl:choose>
          <xsl:when test="$depth=0">FOLDER</xsl:when>
          <xsl:when test="$risks[1]/*[local-name()=concat('FOLDER', $depth)]">
            <xsl:value-of select="concat('FOLDER', $depth)"/>
          </xsl:when>
          <xsl:otherwise>RISK_x0020_FOLDER</xsl:otherwise>
        </xsl:choose>
      </xsl:variable>

      <!-- Build the folder for $risks[1] -->
      <FOLDER>
        <TITLE>
          <xsl:value-of select="$risks[1]/*[local-name()=$element-name]"/>
        </TITLE>
        <xsl:choose>
          <xsl:when test="$element-name='RISK_x0020_FOLDER'">
            <xsl:apply-templates select="$risks" mode="folder-content"/>
          </xsl:when>
          <xsl:otherwise>
            <!-- Build nested folders for all of the risks in the same folder as $risks[1]. -->
            <xsl:call-template name="folders">
              <xsl:with-param name="depth" select="$depth+1"/>
              <xsl:with-param name="risks" select="$risks[*[local-name()=$element-name]=$risks[1]/*[local-name()=$element-name]]"/>
            </xsl:call-template>
          </xsl:otherwise>
        </xsl:choose>
      </FOLDER>

      <!-- Build sibling folders for the risks that are not in the same folder as $risks[1] -->
      <xsl:call-template name="folder">
        <xsl:with-param name="depth" select="$depth"/>
        <xsl:with-param name="risks"
          select="$risks[not(*[local-name()=$element-name]=$risks[1]/*[local-name()=$element-name])]"/>
      </xsl:call-template>
    </xsl:if>
  </xsl:template>
</xsl:stylesheet>

对于这样的情况，我会避免应用模板。创建一组要处理的事物然后使用递归调用模板进行处理要容易得多。
