在

toc子项

中，我得到的值为

，请告诉我哪里出错了

---

谢谢

我添加了样式表中缺少的以下块（没有它，您的输出不一样）：

并将它们粘贴到

toc子项

模板中的变量定义上，该模板不选择任何内容

我建议您花一些时间重构样式表。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，并且可能只有其原始大小的1/4或更小。从删除重复和不必要的变量开始

更新

这些是我在您发布的XSLT文件中所做的唯一更改，以使其正常工作（从

toc项

模板中复制了

$toc title

和

$refe

定义）：

你能添加一段代码来显示你的预期输出吗？嗨@helderdarocha，很抱歉延迟回复，我已经用预期输出更新了我的问题。感谢您的XSLT样式表有大量代码重复，这使它变得不必要的复杂。你在很多地方做着相同的事情。也许如果您重构它并尝试减少代码重复，您可能会发现错误。我注意到代码引用了样式表中应该存在的某个

元素。您可以忽略

ntw

它只是一个名称空间，您可以注释掉它，我还使用

ntw

数据更新了XSLT。它应该是。至少它在您粘贴到此处的示例中有效。我刚刚替换了这些值，得到了您的输出。可能您的实际样式表还有其他问题。尝试复制您在此处发布的代码，并尝试对其进行转换。
