namespace ConsoleApplication34
{
    class Program
    {
        static void Main(string[] args)
        {
            string input =
            "<root>\n" +
              "<TopLevelMenu ID=\"Imports&amp;FileImports\">\n" +
                "<MenuItem ID=\"ImportsNewImports\" OnClick=\"Imports_NewImports\"/>\n" +
                "<MenuItem ID=\"ImportsOpenImports\" OnClick=\"Imports_OpenImports\"/>\n" +
                "<MenuItem ID=\"Imports-Imports\" />\n" +
                "<MenuItem ID=\"ImportsCloseImports\" OnClick=\"Imports_CloseImports\"/>\n" +
                "<MenuItem ID=\"Imports-Imports\"/>\n" +
                "<MenuItem ID=\"ImportsE&amp;xitImports\" OnClick=\"Imports_ExitImports\"/>\n" +
              "</TopLevelMenu\n>" +
              "<TopLevelMenu ID=\"Imports&amp;EditImports\">\n" +
                "<MenuItem ID=\"ImportsUndoImports\" OnClick=\"Imports_UndoImports\"/>\n" +
                "<MenuItem ID=\"Imports-Imports\"/>\n" +
                "<MenuItem ID=\"ImportsCutImports\" OnClick=\"Imports_CutImports\"/>\n" +
                "<MenuItem ID=\"ImportsCopyImports\" OnClick=\"Imports_CopyImports\"/>\n" +
                "<MenuItem ID=\"ImportsPasteImports\" OnClick=\"Imports_PasteImports\"/>\n" +
                "<MenuItem ID=\"Imports-Imports\"/>\n" +
                "<MenuItem ID=\"ImportsOptionsImports\">\n" +
                  "<MenuItem ID=\"ImportsSub Menu ItemImports\">\n" +
                    "<MenuItem ID=\"ImportsSub Sub Menu ItemImports\"/>\n" +
                  "</MenuItem>\n" +
                "</MenuItem>\n" +
              "</TopLevelMenu>\n" +
            "</root>\n";

            XDocument doc = XDocument.Parse(input);
            var results = doc.Descendants("TopLevelMenu").Elements("MenuItem").Select(y => GetMenu(y)).ToList();

        }
        static object GetMenu(XElement element)
        {
            if (!element.HasElements)
            {
                return element.Attribute("ID").Value;
            }
            else
            {
                return (new { id = element.Attribute("ID").Value, child = GetMenu(element.Element("MenuItem"))});
            }
        }

    }
}
