XElement.GetPrefixOfNamespace Method

Gets the prefix associated with a namespace for this XElement.

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

public string GetPrefixOfNamespace(
	XNamespace ns
)

Parameters

ns
Type: System.Xml.Linq.XNamespace

An XNamespace to look up.

Return Value

Type: System.String
A String that contains the namespace prefix.

This method looks through the XML tree for namespace attributes that are in scope for this element. Namespace prefixes are specified in namespace attributes that are in the XML tree.

If the namespace is the default namespace, and there is no prefix for the namespace, then this method returns null.

The following example creates an XML tree that contains a namespace with a prefix. It then uses this method to retrieve the prefix for the namespace. Notice that this example uses the implicit conversion from string to XNamespace when calling this method.

XElement xmlTree = XElement.Parse("<Root xmlns:aw='http://www.adventure-works.com'/>");
string prefix = xmlTree.GetPrefixOfNamespace("http://www.adventure-works.com");
Console.WriteLine("Prefix: {0}", prefix);

This example produces the following output:

Prefix: aw
