-
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='http://www.adventure-works.com'/>");
XNamespace awNamespace = xmlTree.GetNamespaceOfPrefix("aw");
Console.WriteLine("Namespace: {0}", awNamespace);
When using Visual Basic, you would typically use the GetXmlNamespace Operator (Visual Basic) operator, as follows
Imports <xmlns:aw="http://www.adventure-works.com">
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:
Namespace: http://www.adventure-works.com
