      XmlNode lastNode = doc.DocumentElement.LastChild;
      Console.WriteLine("Last book...");
      Console.WriteLine(lastNode.OuterXml);

      XmlNode prevNode = lastNode.PreviousSibling;
      Console.WriteLine("\r\nPrevious book...");
      Console.WriteLine(prevNode.OuterXml);
  }
}

Imports System.Xml

public class Sample 

  public shared sub Main() 

      Dim doc as XmlDocument = new XmlDocument()

      Dim lastNode as XmlNode = doc.DocumentElement.LastChild
      Console.WriteLine("Last book...")
      Console.WriteLine(lastNode.OuterXml)

      Dim prevNode as XmlNode = lastNode.PreviousSibling
      Console.WriteLine(ControlChars.LF + "Previous book...")
      Console.WriteLine(prevNode.OuterXml)  
  end sub
