Create xml:base attribute with LINQ to XML

Attribute xml:base belongs to namespace http://www.w3.org/XML/1998/namespace. In LINQ to XML this namespace you can get from class property XNamespace.XML. XNamespace.Xml returns namespace http://www.w3.org/XML/1998/namespace.

You can create xml:base atribute in this way:

XElement myEl = new XElement(“Root”,
new XAttribute(XNamespace.XML+”base”, “attributeValue”)
);

The result is:

<Root xml:base=”attributeValue”/>
