从第一个正则表达式开始，创建一个来自数据文件的记录数组，然后循环执行其余的正则表达式以改进结果。
Starting with the first regular expression, create an array of records from the data file, then loop through the remaining regular expressions to refine the results.
用正则表达式解析这些文件同样没有什么大不了的。
Again, it is trivial to parse those files with regular expressions.
用户不能自己输入文件或使用正则表达式。
They wouldn't be allowed to type in a list of files or use some kind of regular expression.
