查询以检索组节点的名称

像这样的东西:

XDocument doc; // populate somehow

// this will give the names as XName
var names = from child in doc.Root.Elements()
            select child.Name;

// if you want just the local (no-namespaces) name as a string, use this
var simpleNames = from child in doc.Root.Elements()
                  select child.Name.LocalName;
