Transform XML and apply XSLT in C#

I searched the internet and found two articles:
first from MSDN

using System;
using System.Xml;
using System.Xml.Xsl;
namespace XSLTransformation
{
   /// Summary description for Class1.
   class Class1
   {
       static void Main(string[] args)
       {
           XslTransform myXslTransform;
           myXslTransform = new XslTransform();
           myXslTransform.Load("books.xsl");
           myXslTransform.Transform("books.xml", "ISBNBookList.xml");

       }
   }
}

The second is from CodeProject

This one is long and you should check it yourself.
