There are many ways to do it, e.g. LINQ over XML. But using Xpath is definitely not dead yet:

class Program
{
    static void Main(string[] args)
    {
        XmlDocument doc = new XmlDocument();
        string xml = @"... your xml ";
        doc.LoadXml(xml);
        // Using SelectNodes with Xpath
        XmlNodeList list = doc.SelectNodes("WinDLN/Program[@ID='2']");
        Console.WriteLine(list.Count); // prints 1
        list = doc.SelectNodes("WinDLN/Program[@ID]");
        Console.WriteLine(list.Count); // prints 3 (selected all IDs)
    }
}

What method you'll choose is most often a matter of taste, select the API you're most comfortable with.
