Hope this helps..

        var productElement = XDocument.Load("product.xml").Root;

        var firstImagePath  = productElement.Element("IMG").Value;
        var sElements = productElement.Elements("S");

        //if you want an object instead of XElements, you can do
        var sElementObjects = sElements.Select(xe => new
                                        {
                                              L = xe.Element("L").Value,
                                              V = xe.Element("V").Value,
                                         });

 XElement productCatalog = 
                   new XElement("PRODUCTCATALOG",

                               from urun in db.TBLP1URUNs
                               select new XElement("PRODUCT",

                                           new XElement("ID", urun.ID),

                                           new XElement("D1", urun.MODEL),

                                           new XElement("D2", urun.URUNACIKLAMA),

                                           new XElement("L1", urun.TBLP1URUNKATEGORI.TREENAME),

                                           new XElement("IMG", db.TBLP1URUNRESIMs.Where(p => p.URUN_ID == urun.ID).First().FILE_NAME),

                                           new XElement("EAN", urun.STOKKODU),

                                           new XElement("ATP", GetUrunStokById(urun.ID)),//STOKMIKTARI

                                           new XElement("DM3", urun.DESI),

                                           from ozellikler in urun.TBLP1OZELLIK_URUNs
                                           select new XElement("S",

                                               new XElement("L", ozellikler.TBLP1OZELLIK.TBLP1OZELLIKTIPI.TIPI),

                                               new XElement("V", ozellikler.TBLP1OZELLIK.OZELLIK))

                                               )
