XmlAttribute.NamespaceURI Property

Gets the namespace URI of this node.

[Visual Basic]
Overrides Public ReadOnly Property NamespaceURI As String
[C#]
public override string NamespaceURI {get;}
[C++]
public: __property String* get_NamespaceURI();
[JScript]
public override function get NamespaceURI() : String;

Property Value

The namespace URI of this node. If the attribute is not explicitly given a namespace, this property returns String.Empty.

Remarks

An attribute does not inherit its namespace from the element it is attached to. If an attribute is not explicitly given a namespace, the namespace URI is considered to be String.Empty.

Example

[Visual Basic, C#, C++] The following example displays information on each of the nodes in the attribute collection.

[Visual Basic] 
Imports System
Imports System.IO
Imports System.Xml

public class Sample

  public shared sub Main()

    Dim doc as XmlDocument = new XmlDocument()
    doc.LoadXml("<book xmlns:bk='urn:samples' bk:genre='novel'>" & _
                "<title>Pride And Prejudice</title>" & _
                "</book>") 

    'Create an attribute collection.
    Dim attrColl as XmlAttributeCollection = doc.DocumentElement.Attributes

    Console.WriteLine("Display information on each of the attributes... ")
    Dim attr as XmlAttribute
    for each attr in attrColl
       Console.Write("{0}:{1} = {2}", attr.Prefix, attr.LocalName, attr.Value)
       Console.WriteLine("   namespaceURI=" + attr.NamespaceURI)
    next

  end sub
end class

       Console.WriteLine("\t namespaceURI=" + attr.NamespaceURI);
    }
