并得到以下代码：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml.Linq;
namespace XMLExperiments
{
class Program
{
static void Main(string[] args)
{
XDocument xml = XDocument.Parse(Properties.Resources.test);
IEnumerable<XElement> items = xml.Descendants()
.Where(el => el.Name.LocalName.Contains("item"));
foreach (XElement item in items)
{
IEnumerable<XAttribute> attrs = item.Attributes()
.OrderBy(at => at.Name.LocalName);
foreach (XAttribute attr in attrs)
Console.WriteLine("Attribute name: {0}", attr.Name.LocalName);
}
Console.ReadKey();
}
}
}
执行后，我得到以下信息：

任何指针？
