using namespace System;
using namespace System::IO;
using namespace System::Xml;
int main()
{
   XmlDocument^ doc = gcnew XmlDocument;
   doc->LoadXml( "<book genre='novel' ISBN='1-861001-57-5'><title>Pride And Prejudice</title></book>" );
   XmlElement^ root = doc->DocumentElement;
   
   // Remove all attributes from the root element.
   root->RemoveAllAttributes();
   Console::WriteLine( "Display the modified XML..." );
   Console::WriteLine( doc->InnerXml );
}


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

public class Sample
{
  public static void Main()
  {

    XmlDocument doc = new XmlDocument();
    doc.LoadXml("<book genre='novel' ISBN='1-861001-57-5'>" +
                "<title>Pride And Prejudice</title>" +
                "</book>");

    XmlElement root = doc.DocumentElement;

    // Remove all attributes from the root element.
    root.RemoveAllAttributes();

    Console.WriteLine("Display the modified XML...");
    Console.WriteLine(doc.InnerXml);
  }
}

Imports System.IO
Imports System.Xml

public class Sample

  public shared sub Main()

    Dim doc as XmlDocument = new XmlDocument()
    doc.LoadXml("<book genre='novel' ISBN='1-861001-57-5'>" & _
                "<title>Pride And Prejudice</title>" & _
