XElement.GetNamespaceOfPrefix Method

Gets the namespace associated with a particular prefix for this XElement.

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

public XNamespace GetNamespaceOfPrefix(
	string prefix


Type: System.String

A string that contains the namespace prefix to look up.

Return Value

Type: System.Xml.Linq.XNamespace
An XNamespace for the namespace associated with the prefix for this XElement.

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.

The following example creates an XML tree that has a namespace with an associated prefix. It then uses this method to retrieve the XNamespace for the prefix.

XElement xmlTree = XElement.Parse("<Root xmlns:aw=''/>");
XNamespace awNamespace = xmlTree.GetNamespaceOfPrefix("aw");
Console.WriteLine("Namespace: {0}", awNamespace);

When using Visual Basic, you would typically use the GetXmlNamespace Operator operator, as follows

Imports <xmlns:aw="">

Module Module1
    Sub Main()
        Dim xmlTree As XElement = <aw:Root/>
        Dim awNamespace As XNamespace = GetXmlNamespace(aw)
        Console.WriteLine("Namespace: {0}", awNamespace)
    End Sub
End Module

This example produces the following output:


Windows 7, Windows Vista, Windows XP SP2, Windows Server 2008 R2, Windows Server 2008, Windows Server 2003, Windows CE, Windows Mobile for Smartphone, Windows Mobile for Pocket PC, Xbox 360, Zune
