   Console::WriteLine( "\t namespaceURI={0}", elem->NamespaceURI );
}

// This code produces the following output.
// bk:ISBN = 1-861001-57-5  namespaceURI=urn:samples

using System;
using System.IO;
using System.Xml;

public class Sample
{
  public static void Main()
  {

    XmlDocument doc = new XmlDocument();
    doc.LoadXml("<book xmlns:bk='urn:samples'>" +
                "<bk:ISBN>1-861001-57-5</bk:ISBN>" +

    // Display information on the ISBN element.
    XmlElement elem = (XmlElement) doc.DocumentElement.FirstChild;
    Console.Write("{0}:{1} = {2}", elem.Prefix, elem.LocalName, elem.InnerText);
    Console.WriteLine("\t namespaceURI=" + elem.NamespaceURI);
  }
}

// This code produces the following output.
// bk:ISBN = 1-861001-57-5  namespaceURI=urn:samples

                "<bk:ISBN>1-861001-57-5</bk:ISBN>" & _
                "<title>Pride And Prejudice</title>" & _
                "</book>")

    ' Display information on the ISBN element.
    Dim elem as XmlElement 
    elem = CType(doc.DocumentElement.ChildNodes.Item(0),XmlElement) 
    Console.Write("{0}:{1} = {2}", elem.Prefix, elem.LocalName, elem.InnerText)
    Console.WriteLine("  namespaceURI=" + elem.NamespaceURI)
  end sub
end class

' This code produces the following output.
' bk:ISBN = 1-861001-57-5  namespaceURI=urn:samples
