There are many Item tags in this XML file how do I refer to the one that i need and get the text inside that description tag?

Answer 1

you may do something like this read all the description to a list and then get specific description from a list

    var rss = XDocument.Load("your rss file");
    var items = (from c in rss.Descendants("item") select new{
                 Title  = (string)c.Element("description")      
                }).ToList();

// first description 

    string firstitem= items[0].Title.ToString();
