这里我想要实现的是，首先捕获toc-title，然后通过XML文档进行搜索，找到toc-title后我需要获取para num {1}}关注它。在我的XSLT中，它适用于toc-item，但在使用toc-subitem时，它会拉错值，而下面是我得到的输出的一部分。
<table class="toc-item-first-level">
<tbody>
<tr>
<td class="toc-item-num"></td>

在toc-subitem中，我将值设为<a href="LRSC_CH_0/P">，请告诉我哪里出错了。
由于
答案 0 :(得分：1)
我添加了样式表中缺少的以下块（没有它你的输出不一样）：
<ntw:words>
<ntw:nums num="1" word="first" />
<ntw:nums num="2" word="second" />
</ntw:words>
我注意到你的代码有很多代码重复，这是一个常见的错误来源。还有许多不必要的变量，这增加了复杂性。我检查了项目和子项目模板之间的差异，并注意到正在使用upper-case()函数测试字符串的那个，而另一个不是（它也略有不同，尽管t似乎指的是相同的元素）。所以我从不起作用的模板中替换了$toc-title和$refe变量定义，在其位置粘贴了您正在使用的模板中使用的完全相同的代码，并且正确地复制了值
为了解决您的问题复制这两个变量的定义来自toc-item模板：
<xsl:variable name="toc-title" select="current()/toc-title/*" />
<xsl:variable name="refe">...</xsl:variable>
并将其粘贴到toc-subitem模板中那些不会选择任何内容的变量的定义上。
我建议您花一些时间来重构样式表。您将更好地理解它是如何工作的，它将变得更简单，更不容易出错，并且可能具有原始尺寸的1/4或更小。首先删除重复和不必要的变量。
<强>更新
这些是我在您发布的XSLT文件中所做的仅更改，以使其正常工作（从$toc-title模板复制了$refe和toc-item个定义）：
<xsl:stylesheet ...> ...
<xsl:template match="toc-subitem">
...
<xsl:variable name="toc-title" select="upper-case(current()/toc-title/text())" />
...
<xsl:variable name="refe">
<xsl:choose>
<xsl:when test="//section[title/*[upper-case(text()) = $toc-title]]/section[1]/para[1]/@num">
<xsl:value-of select="//section[title/*[upper-case(text()) = $toc-title]]/section[1]/para[1]/@num[1]"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="//section[title/*[upper-case(text()) = $toc-title]]/para[1]/@num[1]"/>
