Travellers get from one side to the other by walking across a footbridge that spans a little stream.
旅游者通过一座横跨小溪的人行桥从一边走到另一边。
If a program (such as a terminal emulator) connects to that port, it will get the stream from the mainframe through the connection. Whatever it sends to the connection will go to the next program...
如果程序(例如终端模拟器)连接到该端口,就会通过该连接得到来自主机的流。
You can, for instance, use XMLReader, a stream parser, to get an element, import it into the DOM and extract data using XPath.
比方说,可以使用流解析器XMLReader获取一个元素,将其导入DOM,然后用XPath提取数据。
