In my case I want to go through all available dates.that means when user select a date[from the form], then according to that date ,other data should provide.to do that I have to look through all available dates.how can I do that. this is my code in MVC.

    public void getDatas(string destination, string cruisetype, string datetime)          {              XElement rootele = XElement.Load(Server.MapPath("~/XmlFiles/CruiseData/cruiseprodutstwo.xml"));                var selecttoDate = rootele.Elements("Cproducts").Elements("Availability").Elements("Departure").Elements("Date"); //here I want to get the data that the [date == datetime]
