我试图遍历父节点的distinct子元素。框架预期的xml 以下是我的xml。 

<NewDataSet>
<caseParticipants>
<Litigants>PORTFOLIO RECOVERY ASSOCIATES</Litigants>
<Attorneys>MANISCALCO, ANTHONY JOSEPH</Attorneys>

</NewDataSet>

我需要转换为xml，如下所示。

我只为caseParticipant尝试过如下所示的一个部分。我需要为所有节点做这样的事情而不给出元素名称。因为我每次都得到不同类型的父母和孩子的元素。

XSLT代码：

<xsl:template match="caseParticipants">
<xsl:variable name="vrtfEvalResult">
 <xsl:call-template name="eval">
   <xsl:with-param name="pPath" select="'/NewDataSet/caseParticipants'"/>
 </xsl:call-template>
</xsl:variable>
<row>
<cell id="1"><xsl:value-of select="Litigants" /></cell>
<cell id="2"><xsl:value-of select="Attorney" /></cell>
</row>
</xsl:template>
 <xsl:template match="text()"/>
 <xsl:template match="Path" name="eval">
<xsl:param name="pPath" select="."/>
<xsl:param name="pContext" select="/"/>
<xsl:choose>
<!-- If there is something to evaluate -->
<xsl:when test="string-length($pPath) >0">
  <xsl:variable name="vPath" select=
      "substring($pPath,2)"/>
  <xsl:variable name="vNameTest">
   <xsl:choose>
    <xsl:when test="not(contains($vPath, '/'))">
     <xsl:value-of select="$vPath"/>
    </xsl:when>
    <xsl:otherwise>
     <xsl:value-of select=
         "substring-before($vPath, '/')"/>
    </xsl:otherwise>
   </xsl:choose>
  </xsl:variable>
  <xsl:call-template name="eval">
   <xsl:with-param name="pPath" select=
     "substring-after($pPath, $vNameTest)"/>
   <xsl:with-param name="pContext" select=
    "$pContext/*[name()=$vNameTest]"/>
  </xsl:call-template>
  </xsl:when>
 <!-- Otherwise we have evaluated completely the path -->
 <xsl:otherwise>
 <xsl:copy-of select="$pContext"/>
 </xsl:otherwise>
 </xsl:choose>
 </xsl:template>

我不得不重新考虑这一点以使其正常工作，但我认为这就是你想要的：

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
  <xsl:output method="xml" omit-xml-declaration="yes" indent="yes" />
  <xsl:key name="distinct-second-level-elements" match="/*/*" use="local-name()" />
  <xsl:template match="/NewDataSet">
    <searchResults>
      <caseDetails>
        <xsl:for-each select="*[count(.|key('distinct-second-level-elements', local-name())[1]) = 1]">
          <xsl:variable name="currNodeName" select="local-name()" />
          <xsl:element name="{$currNodeName}">
            <xsl:attribute name="Label">
              <xsl:value-of select="substring-after($currNodeName, 'case')" />
            </xsl:attribute>
            <row>
              <xsl:for-each select="./*">
                <colhead id="{position()}" align="left" bold="no">
                  <xsl:value-of select="local-name(.)" />
                </colhead>
              </xsl:for-each>
            </row>
            <xsl:for-each select="//*[local-name() = $currNodeName]">
              <row>
                <xsl:for-each select="./*">
                  <cell id="{position()}">
                    <xsl:value-of select="." />
                  </cell>
                </xsl:for-each>
              </row>
            </xsl:for-each>
          </xsl:element>
        </xsl:for-each>
      </caseDetails>
    </searchResults>
  </xsl:template>
  <xsl:template match="text()" />
</xsl:stylesheet>
  1. 使用密钥获取不同的二级节点名称，并遍历该密钥la Muenchian Grouping - 这显然是我现在在XSLT标记中写的所有内容;）
  2. 在那里嵌套更多for-each es以获取具有相同名称和布局行/单元格的其他节点的子节点

    3. 所有这一切都是使用像local-name()和深度选择器（例如/*/*）这样的东西完成的，所以只要你的结构保持一致，无论节点名称它都应该有效

    一个注意事项 - id attributes should be unique in a document，所以这在技术上不是有效的XML - 但我认为这只是下游消费者的要求，他们没有严格遵循标准。如果不是这种情况，您应该尽可能为该属性选择一个不同的名称。
