小编Xap*_*Xap的帖子

我有以下XML:

    <root>
 <groups>
  <group id="101">
   <number>10</number>
   <children>
    <leader id = "A" />
    <members>
     <member id="1">
     <member id="2">
     <member id="3">
    </members>
   </children>
  </group>
  <group id="102">
   <number>20</number>
   <children>
    <leader id = "A" />
    <members>
     <member id="4">
     <member id="5">
     <member id="3">
    </members>
   </children>
  </group>
  <group id="103">
   <number>30</number>
   <children>
   <leader id = "A" />
    <members>
     <member id="1">
     <member id="4">
     <member id="3">
    </members>
   </children>
  </group>
 </groups>

</root>

如何使用XSL对id = 1的所有成员的属性进行求和？

谢谢

我有一个C#类执行无限循环,直到条件变量设置为true.还有另一个等待网络消息的类,当接收到消息时,调用另一个类将条件变量修改为true,这样就可以退出while循环.等待消息是在一个单独的线程中完成的:

修饰符类:

public class Modifier{
Otherclass log;
private static NetworkStream theStream;
private StreamReader theInput;

public Modifier(Otherclass other, NetworkStream str)
            {
                this.log = other;
                theStream = str;
                theInput = new StreamReader(theStream);
                Thread listenThread = new Thread(new ThreadStart(listen));
                listenThread.Start();
            }

            public void listen()
            {
                while (true)
                {
                    log.postMessage(theInput.ReadLine());
                }
            }
}

而另一类:

public class Otherclass{
    bool docontinue = true;
    public void postMessage(string input)
    {
         docontinue = true;
    }

    public void wait()
    {
          while(!docontinue)
          {
          }
    }
}

问题是虽然发送了一条消息,程序仍然停留在while(!docontinue).我怀疑问题是变量docontinue没有被修改但我不知道问题是否在其他地方.
