使用 re 模块，例如：

  ... 
字符串= AAPL，2010年5月7日15：58,21.34,21.36,21.34,21.35,525064\n，
 RegExp = ^ AAPL，*，
例re：run（String，RegExp）
 {match，Captured}-> ...; 
 nomatch-> ... 
结尾，
 ... 
 

How would I do regex matching in Erlang?

All I know is this: f("AAPL" ++ Inputstring) -> true.

The lines that I need to match "AAPL,07-May-2010 15:58,21.34,21.36,21.34,21.35,525064\n"

In Perl regex: ^AAPL,* (or something similar)

In Erlang?

Use the re module, e.g.:

...
String = "AAPL,07-May-2010 15:58,21.34,21.36,21.34,21.35,525064\n",
RegExp = "^AAPL,*",
case re:run(String, RegExp) of
  {match, Captured} -> ... ;
  nomatch -> ...
end,
...
