Thats what I am trying… needs direction…

 var Doc = XDocument.Load("Info.xml");
    var items = from i in Doc.Descendants("Section")
                select new
                {
                  ID = p.Element("ID").Value
                }
    foreach (var item in items)
          item.id = "VALUE"
??????

Answer 1

You are currently creating a list of anonymous type objects with

 from i in Doc.Descendants("Section")
 select new { ... }

Instead, create a list of elements to update:

var items = from i in Doc.Descendants("Section")
     select i;

foreach (var item in items)
{
   item.Element("ID").Value = "VALUE";
   item.Element("Foo").Value = "Foo";
}
Doc.Save(...);

Note that XML is case-sensitive.
