  var results = (from s in doc.Descendants("RTInventorys")
                       where s.Element("RTInventory").Element("Result").Value =="1"
                       select s);

这个要把节点值为2的节点过滤掉代码是这样写吗

var results = (from s in doc.Descendants("RTInventorys")
where s.Element("RTInventory").Element("Result").Value =="1"
select s);

                                        你这个不是选中节点为1的值么
