我从转换得到的输出具有第一块是与嵌套正确的，但我无法弄清楚如何防止看着它已经处理节点的转换。有很多重复，这正是我想要消除的。我一直试图弄清楚这个问题一个多星期了，真的可以用一些帮助。在此先感谢所有XML/XSLT专家。

此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="risks"/> 
    <FOLDERS> 
     <xsl:call-template name="folder">

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

    <!--

    the template creates more folders at the same depth, by calling itself with

    <xsl:template name="folder">

    <xsl:param name="risks"/> 
    <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。创建一组要处理的内容然后使用递归调用模板执行处理要容易得多。
