请问一下如何解析XML文档?

Question

各位高手：
    请问一下如何解析XML文档:
假如我有一个XML文档是这样的:
<people>
   <people1>
        <name>
           people1
        </name>
        <age>
           23
        </age>
   </people1>
   <people2>
         <name>
            people2
         </name>
         <age>
            20
         </age>
   </people2>
</people>
假如现在我想取得people1的age的值.如何实现?

string temp = doc.SelectSingleNode("people/people1/age").InnerText;
