 virtual System::String ^ GetPrefixOfNamespace(System::String ^ namespaceURI);
public virtual string GetPrefixOfNamespace (string namespaceURI);
abstract member GetPrefixOfNamespace : string -> string
override this.GetPrefixOfNamespace : string -> string
Public Overridable Function GetPrefixOfNamespace (namespaceURI As String) As String

   "<title>Pride And Prejudice</title>"
   "</book>" );
   XmlNode^ root = doc->FirstChild;
   
   //Create a new node.
   String^ prefix = root->GetPrefixOfNamespace( "urn:samples" );
   XmlElement^ elem = doc->CreateElement( prefix, "style", "urn:samples" );
   elem->InnerText = "hardcover";
   
   //Add the node to the document.
   root->AppendChild( elem );
   Console::WriteLine( "Display the modified XML..." );
   doc->Save( Console::Out );
}
