using System.Xml.Xsl;
public partial class xmlTesting : System.Web.UI.Page
{
   protected void Page_Load(object sender, EventArgs e)
   {
       XPathDocument xPathDoc = new XPathDocument(Server.MapPath("books.xml"));
       XslTransform xTrans = new XslTransform();
       xTrans.Load(Server.MapPath("Books.xsl"));

       StringWriter Sw = new StringWriter();

       xTrans.Transform(xPathDoc, null, Sw);

       ltr1.Text = Sw.ToString();
   }
