XDocument Contacts = XDocument.Load("XMLFile1.xml");
//XElement Contacts = XElement.Parse(xmldata);
var Elist = from t in Contacts.Descendants("HEADER")
select new
{
CREATION_DATE = t.Element("CREATION_DATE").Value.Replace("\n", ""),
ITEM_NUMBER = t.Element("ITEM_NUMBER").Value.Replace("\n", ""),
ITEM_DESC = t.Element("ITEM_DESC").Value.Replace("\n", ""),
ITEM_CATEGORY_CODE = t.Element("ITEM_CATEGORY_CODE").Value.Replace("\n", ""),
PRIMARY_UOM_CODE = t.Element("PRIMARY_UOM_CODE").Value.Replace("\n", "") //注意此处用到 attribute
};

XDocument Contacts =XDocument.Load("XMLFile1.xml");

//XElement Contacts = XElement.Parse(xmldata);

var
Elist =from t in Contacts.Descendants("HEADER")
