XNamespace.Xml Property

Gets the XNamespace object that corresponds to the XML URI (http://www.w3.org/XML/1998/namespace).

Namespace:  System.Xml.Linq
Assembly:  System.Xml.Linq (in System.Xml.Linq.dll)

public static XNamespace Xml { get; }

Property Value

Type: System.Xml.Linq.XNamespace
The XNamespace that corresponds to the XML URI (http://www.w3.org/XML/1998/namespace).

Certain standardized attributes, such as space, are in the http://www.w3.org/XML/1998/namespace namespace. The W3C standard specifies that this namespace does not have to be declared as an attribute in the XML tree. It is a reserved namespace that is always automatically available in the XML parser.

The following example shows how to create an xml:space="preserve" attribute in an XML tree:

XElement root = new XElement("Root",
    new XAttribute(XNamespace.Xml + "space", "preserve"),
    new XElement("Child", "content")
);
Console.WriteLine(root);

This example produces the following output:

<Root xml:space="preserve">
  <Child>content</Child>
</Root>
