基于下面的源 XML，我想捕获<emphasis>不包含<emphasis bold="yes">NOTE#:的文本节点和元素</emphasis>，以及它们对应的<emphasis bold="yes">NOTE#:</emphasis>元素。

源 XML：

<section>
  <para>
    <emphasis bold="yes">NOTE1:</emphasis> This is the text of the first note 1 <emphasis bold="yes">that should only be in the <emphasis italic="yes">first</emphasis> subsection occurance of note one.</emphasis>. This is the second sentence of the first note one. <emphasis italic="yes">Here is some other text</emphasis> that can appear. <emphasis bold="yes">Marvin Gaye is an excellent musician1.</emphasis> Play it for your girlfriend1 <emphasis italic="yes">now1.</emphasis>.
    <emphasis bold="yes">NOTE2:</emphasis> This is the text of  the first note two2.1 <emphasis italic="yes">The Isley Brothers are also good.2.1</emphasis>
    <emphasis bold="yes">NOTE1:</emphasis> This is the text of the second note one.1.2 <emphasis italic="yes">My girlfriend loves them1.2</emphasis>
    <emphasis bold="yes">NOTE3:</emphasis> This is the text of the first note three3.1.
    <emphasis bold="yes">NOTE1:</emphasis> This is the text of the third note one.1.3<emphasis italic="yes">She is going to make me dinner tonight1.3</emphasis>
    <emphasis bold="yes">NOTE3:</emphasis> This is the text of the second note three.3.2<emphasis italic="yes">Steak and potatos3.2</emphasis>
    <emphasis bold="yes">NOTE2:</emphasis> This is the text of the second note two.2.2<emphasis italic="yes">And then some wine2.2</emphasis>
  </para>

如果我正确理解您的要求，我认为您的 XSLT 可能有点过于复杂。看起来您只是想对节点进行分组，每个组的开头由带有文本状态“NOTE”的强调节点表示

假设您使用的是 XSLT 2.0（因为您当前的 XSLT 标记为 version="2.0"）然后向有用的xsl:for-each-group命令打个招呼，这应该正是您所需要的。在您的情况下，以相关的强调元素开始对节点进行分组：

<xsl:for-each-group 
    select="node()" 
    group-starting-with="emphasis[starts-with(text(), 'NOTE')]">

在其中，您将输出您的subsection和para元素，然后遍历组中的元素以复制它们

<xsl:apply-templates select="current-group()" />

您将使用XSLT 标识转换来输出强调元素本身。

这是令人愉快的短得多的 XSLT

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
   <xsl:output method="xml" indent="yes"/>
   <xsl:strip-space elements="*"/>

   <xsl:template match="para">
      <para>
         <xsl:for-each-group select="node()" group-starting-with="emphasis[starts-with(text(), 'NOTE')]">
            <subsection>
               <para>
                  <xsl:apply-templates select="current-group()" />
               </para>
            </subsection>
         </xsl:for-each-group>
      </para>
   </xsl:template>

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

当应用于您的 XML 时，将输出以下内容

<section>
   <para>
      <subsection>
         <para>
            <emphasis bold="yes">NOTE1:</emphasis> This is the text of the first note 1 
            <emphasis bold="yes">that should only be in the 
               <emphasis italic="yes">first</emphasis>subsection occurance of note one. 
            </emphasis>. This is the second sentence of the first note one. 
            <emphasis italic="yes">Here is some other text</emphasis>that can appear. 
            <emphasis bold="yes">Marvin Gaye is an excellent musician1.</emphasis>Play it for your girlfriend1 
            <emphasis italic="yes">now1.</emphasis>. 
         </para>
      </subsection>
      <subsection>
         <para>
            <emphasis bold="yes">NOTE2:</emphasis>This is the text of the first note two2.1

      </subsection>
      <subsection>
         <para>
            <emphasis bold="yes">NOTE3:</emphasis> This is the text of the second note three.3.2
