You can also do it quite easily using Extensible Stylesheet Language (XSL) without any C# code.

You could do it like this: using System; using System.IO; using System.Linq; using System.Xml.Linq; class Test { static void Main() { XElement catalog = XElement.Load(jitendra.xml); string[] authors = (from element in catalog.Elements(book).Elements(author) select element.Value).ToArray(); string[] titles = (from element in catalog.Elements(book).Elements(title) select element.Value).ToArray(); File.WriteAllLines(authors.txt authors); File.WriteAllLines(titles.txt titles); } }
