如何用C#获取XML中的任意节点值,比如：
  <aaa name="book" value="0">
    <key name="we" value="111" />
  </aaa>
  <bbb name="dictionary" value="1">
    <key name="fg" value="222" />
  </bbb>
  <ccc name="Magazine" value="2">
    <key name="hj" value="333" />
  </ccc>

不是子节点，是根节点？
用xmlNode.NextSibling.Name只能得到下一个节点值，如果要得到第三个或第四个怎么获取？

reader = new XmlTextReader("*.xml");

while (reader.Read())

            } 
 
            Console.ReadKey();

} 

不知道对你有没有帮助。
我是通过递归把Xml的节点全部遍历，然后按照顺序编号...要其他的信息可以自己加。
