         reader.MoveToContent()
         reader.MoveToFirstAttribute()
         Dim genre As String = reader.Value
         Console.WriteLine("The genre value: " & genre)
      
      Finally
         If Not (reader Is Nothing) Then

Starting with the .NET Framework 2.0, we recommend that you create XmlReader instances by using the XmlReader.Create method to take advantage of new functionality.
