c# - 如果使用 XML 前缀，则 XSLT 转换只会导致页面标题 h1::Documents 以 html 格式打印

Question

我不熟悉使用 xslt 将 xml 转换为 html。我不是

这导致只有页面标题 h1::Documents 以 html 格式打印。相同的模板 xslt 和 C# 代码将适用于直接的 xml，但它似乎不适用于带有前缀 dme 的文档:

XML:

Answer 1

由于前缀的原因，您的模板与您的元素不匹配 - 换句话说，您正在匹配 Document , 不是 dme:Document ;就 XSLT 而言，它们不是相同的元素名称。

实际上，我认为唯一的方法是让你的模板匹配 *[local-name()='Document'] , 而不仅仅是 Document .

如果您使用的是 XSLT2 或更高版本，则有 xpath-default-namespace="dme"您可以在样式表上设置属性，但这不是 C# 中的一个选项，除非您使用第三方库(如 Saxon)。您最好的选择可能是修改您的 XSLT 以忽略使用 local-name 的命名空间。欺骗或预处理您的 XML 以首先删除命名空间。

编辑:刚刚注意到您还有 <xsl:apply-templates select="Document"/>在那里，也需要更新为 select="*[local-name()='Document']" .
