You could use a XDocument:

class Program
{
    static void Main()
    {
        var doc = XDocument.Load("test.xml");
        var key = doc
            .Descendants("setting")
            .Descendants("key")
            .FirstOrDefault(x => x.Attribute("name").Value == "ankit");
        if (key != null)
        {
            key.Attribute("value").Value = "yes";
        }
        doc.Save("new.xml");
    }
}
