yes it's very simple but does satisfy my need. Thank you very much!
 
actually I had spent time researching the regex packages on Hackage, it seems they doesn't provide such APIs for replace, but from my point of view the use of *replace* is as imporant as *match* in regular expression. Or I didn't find the right place?
 
Thanks again!
