我有XML文档的以下部分。当我在这个XML文档上运行xslt时，col类。。。colgroup内部被调用，colgroup被调用，但col类的结束标记没有被调用。请让我知道如何关闭col课堂。。。最后一段代码包含我的xml html输出。

感谢
欢迎使用堆栈溢出！
样式表没有指定输出方法，但是您的输出是可识别的HTML。所以样式表使用的是HTML输出方法，而不是XML输出方法。在HTML输出方法中，始终为空的元素（如col）使用SGML样式的结束标记，因此显示的输出是正确的。
如果您想要XML输出，请将xsl:output元素添加到样式表中（作为xsl:stylesheet的第一个子元素），并在其上指定method="xml"，从而：
<xsl:output method="xml"/>
（请注意，如果您希望创建XHTML输出，则需要将输出元素放在XHTML命名空间中。）
当我向样式表中添加一个输出元素时，输出中的colgroup元素采用以下形式，这似乎就是您想要的：
<colgroup>
<col class="colnum-1 colname-col1 colwidth-18"/>
<col class="colnum-2 colname-col2 colwidth-82"/>
</colgroup>
