c# - 将具有相同地址的多个命名空间添加到 XDocument

Question

我需要将多个 namespace 添加到具有相同地址的 xdocument (C#)

<root xmlns:f="urn://xml.voodoo.net/vd/formating-1.0" xmlns="urn://xml.voodoo.net/vd/formating-1.0">
 <a:something>stuff and more stuff</a:something>
</root>

如果我使用下面的代码添加..它只显示 xmlns:f

XNamespace defaultNS = "urn://xml.voodoo.net/vd/formating-1.0";
XNamespace f = "urn://xml.voodoo.net/vd/formating-1.0";


XElement rootElement = new XElement(defaultNS + "root",
new XAttribute(XNamespace.Xmlns + "f", f.NamespaceName),

如何显示 2 个命名空间？？有可能吗？

Answer 1

var doc = new XDocument(
    new XElement(defaultNS + "root",

        new XAttribute(XNamespace.Xmlns + "f", defaultNS),
        new XAttribute("xmlns", defaultNS),
        new XElement(defaultNS + "something",
            new XAttribute(XNamespace.Xmlns + "f", defaultNS), "stuff and more stuff")
            )
    );

期望的输出:

<root xmlns:f="urn://xml.voodoo.net/vd/formating-1.0" xmlns="urn://xml.voodoo.net/vd/formating-1.0">
  <f:something xmlns:f="urn://xml.voodoo.net/vd/formating-1.0">stuff and more stuff</f:something>
</root>
