元素数据存储在属性中，一些数据甚至由管道符或分号分隔。
Element data is stored in attributes, and some data is even delimited with pipe symbols or semicolons.
在管道符后面，切换到另一个目录，然后从标准输入提取字节流。
After the pipe, change to a different directory and then extract the byte stream again from the standard input.
看一下管道符前面的代码，它创建文件的字节流并发送到标准输出。
In looking at the previous code before the pipe, a byte stream of the files is created on the standard output.
