下列範例會顯示最後兩本書籍。

#using <System.Xml.dll>

using namespace System;
using namespace System::Xml;
int main()
{
   XmlDocument^ doc = gcnew XmlDocument;
   doc->Load( "books.xml" );
   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 );
}

using System;
using System.Xml;

public class Sample5
{
    public static void Main()
    {
        XmlDocument doc = new XmlDocument();
        doc.Load("books.xml");

        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()
      doc.Load("books.xml")

      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
end class
