使用C#在XML文档中查找特定值的好方法是什么？

using System;
using System.Xml.Linq;

class Program
{
    static void Main()
    {
        string xml = @"<root>
                          <item>
                            <name>Item 1</name>
                           <value>10</value>
                          </item>
                          <item>
                            <name>Item 2</name>
                           <value>20</value>
                          </item>
                          <item>
                            <name>Item 3</name>
                           <value>30</value>
                          </item>
                        </root>";

        XElement root = XElement.Parse(xml);

        var items = from item in root.Descendants("item")
                    where (string)item.Element("name") == "Item 2"
                    select item;

        foreach (var item in items)
        {
            Console.WriteLine("Value of {0} is {1}", (string)item.Element("name"), (int)item.Element("value"));
        }
    }
}
