我有以下一组 XML 列表的代码，我正在使用以下 XSLT 来提取内容，但它不起作用。第一个和最后一个工作正常，但中间一个会产生问题。任何帮助请......

您的所有sa-item元素都只有一个question孩子，因此

cl:sa-item[not(position() = last())]/cl:question[not(position()=last())]

永远不会匹配任何东西（因为在question谓词中两者都position()将last()始终为 1）。您可能只需要删除question步骤上的谓词，即让您的模板只检查 的索引sa-item，而不是question元素。最干净的方法是优先考虑：

<xsl:template priority="3" match="cl:sa-item[1]/cl:question/cl:para">
  <!--...-->
</xsl:template>

<xsl:template priority="2" match="cl:sa-item[last()]/cl:question/cl:para">
  <!--...-->
</xsl:template>

<xsl:template priority="1" match="cl:sa-item/cl:question/cl:para">
  <!--...-->
</xsl:template>

这样，第一个模板将拾取第一个，第二个将sa-item拾取last()（假设它不是第一个，如果只有一个项目），第三个将拾取第一个未消耗的任何其他模板两个更高优先级的模板。short-answer-section
