使用XDocument生成具有多个名称空间的XML

我有这样的XML:

<stream:stream to="lap-020.abcd.co.in" from="sourav@lap-020.abcd.co.in" xml:lang="en" xmlns="jabber:client" xmlns:stream="http://etherx.jabber.org/streams" version="1.0"/>

尝试使用XDocument生成XML

private readonly XNamespace _streamNamespace = "http://etherx.jabber.org/streams";
private readonly XName _stream;

_stream = _streamNamespace + "stream";

XDocument xdoc=new XDocument(
    new XElement(_stream,
        new XAttribute("from", "sourav@lap-020.abcd.co.in"),
        new XAttribute("to","lap-020.abcd.co.in"),
        new XAttribute("xmlns:stream","http://etherx.jabber.org/streams"),
        new XAttribute("version","1.0"),
        new XAttribute("xml:lang","en")
      ));

但我得到一个例外:

  

附加信息:':'字符,十六进制值0x3A,不能包含在名称中。

要添加名称空间声明,您可以使用XNamespace.Xmlns,并使用xml来引用预定义的名称空间前缀XNamespace.Xml,例如:

XNamespace stream = "http://etherx.jabber.org/streams";
var result = new XElement(stream + "stream",
                    new XAttribute("from", "sourav@lap-020.abcd.co.in"),
                    new XAttribute("to","lap-020.abcd.co.in"),
                    new XAttribute(XNamespace.Xmlns + "stream", stream),
                    new XAttribute("version","1.0"),
                    new XAttribute(XNamespace.Xml+"lang","en"),
                    String.Empty);
Console.WriteLine(result);
//above prints :
//<stream:stream from="sourav@lap-020.abcd.co.in" to="lap-020.abcd.co.in" 
//               xmlns:stream="http://etherx.jabber.org/streams" version="1.0" 
//               xml:lang="en">
//</stream:stream>

您可以添加名称空间,如

 XElement root = new XElement("{http://www.adventure-works.com}Root",
    new XAttribute(XNamespace.Xmlns + "aw", "http://www.adventure-works.com"),
    new XElement("{http://www.adventure-works.com}Child", "child content")
);

此示例生成以下输出:

    <aw:Root xmlns:aw="http://www.adventure-works.com">
  <aw:Child>child content</aw:Child>
</aw:Root>
