xml读取节点属性问题
初学，麻烦大家指导一下，xml文件如下
<?xml   version= "1.0 "   encoding= "utf-8 "   ?>
<processes>
    <process   id= "1 "   name= "请假流程 "   >
        <activity   id= "start "   name= "开始 "   activityType= "1 ">
            <state> 0 </state>
            <people>   qq   </people>
            <Transition   number= "1 "   joinType= "and   ">
                <nextActivity   id= "A "   />
            </Transition   >
        </activity>
        <activity   id= "A "   name= "部门审核 "   activityType= "1 ">
            <state> 0 </state>
            <people>   uu   </people>
            <Transition   number= "1 "   joinType= "and   ">
                <nextActivity   id= "B "   />
            </Transition   >
        </activity>
              <activity   id= "End "   name= "结束 "   activityType= "1 ">
            <state> 0 </state>
        </activity>
    </process>
</processes>  
我想显示结果如下start-A-B   ，start,A,   B分别放在lable   里，用xmldocment   ,没有查到相关用法，请教一下，有点着急！
  protected   void   Page_Load(object   sender,   EventArgs   e)
        {
                XmlDocument   xdoc   =   new   XmlDocument();
                xdoc.Load   =   Xdoc.Load(Server.MapPath( "work.xml "));
               
                ???......

        }
