如果在其他地方得到解答，我会道歉，我确实看了相关的问题，但看不出它们与此有什么关系。

我有一个这样的文件：

是否可以编写一个经过并合并所有Pts的xlst？在这种情况下，这将导致使用相同Pt项的第二项名称。他们使用的ID并不重要。每个Nd都会引用一个Pt，而不是每个Pt都会有ND引用它，并且Pts可以有多个Nds引用它们

感谢您提出任何指示，我对这些事情毫无希望！

使得2 Nd项与具有相同名称但不同ID的2个Pt项的关系被组合成具有仅与一个Pt项的关系的2个Nd项。只要将关系合并到第一个PT中，就可以删除第二个PT，这样就不会有重复但关系仍然完好无损？

我写了以下样式表：

<xsl:stylesheet
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    version="1.0">

<xsl:key name="k1" match="term[termType = 'Pt']" use="termName"/>
<xsl:key name="k2" match="term[termType = 'Pt']" use="termId"/>

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

<xsl:template match="term[termType = 'Pt'][not(generate-id() = generate-id(key('k1', termName)[1]))]"/>

<xsl:template match="term[termType = 'Nd']/relation/termId">
  <xsl:copy>
    <xsl:value-of select="key('k1', key('k2', .)/termName)[1]/termId"/>
  </xsl:copy>
</xsl:template>

</xsl:stylesheet>

所以没有正确解决一个交叉引用，但我认为问题不在于XSLT，而在于您的数据所在的位置<termId>OMITERM9998</termId>，而<termId>OMITERMO9998</termId>的前导0。这有帮助吗？真实数据中的ID是否更好？或者您是否需要编码以去除前导零以匹配/交叉引用元素？
