Once you can send messages between the two machines, sending and receiving any kind of data becomes a simple case of knowing the process ID and the node name.
在两台机器之间发送消息时，发送和接收任意类型的数据都变得极为简单，只需了解进程ID和节点名称即可。
Locate the iw: item node whose ID is gadgetUrl (see figure 17).
找到id为gadgeturl的iw： item节点(见图17)。
In this case, you compare the input node against a node named id that has a child text node made of the name string passed in to the function.
在这种情况下，将输入节点与一个名为id的节点相比较，id节点的子文本节点由传递给函数的Name字符串构成。
