My method gets passed the file name which in this case is AUTHOR so it coinsides with the elements and the ID.


When my code gets to xElement.Elements(file).All(ele => it bypasses it all

        public Boolean deleteXml(String file, int id)
        {
            //file will be AUTHOR or BOOK


            String f = @"files\" + file + ".xml";
            XElement xElement = XElement.Load(f);


            xElement.Elements(file).All(ele =>
            {
                if (ele.Element("ID").Value.Equals(id.ToString()))
                {
                    ele.Remove();
                    xElement.Save(f);
                }
                return true;
            });


            return false;
        }

what is wrong?
thanks
