java - Matching date ranges using Regex -


i need regex match file names, dated logs, , need fetch logs 24th 31st. there 2 type of logs.

log filenames follows:

log_file_first-type_24-03-2013 log_file_second-type_24-03-2013

i have tried following:

log_file_(first|second)\-type_(2,3)(4,1)\-03\-2013

but takes in 21st also, how this?

regular expressions powerful, have several limitations. there not in integers' ranges. not elegant solution, works:

log_file_(first|second)\-type_(2[4-9]|30|31)\-03\-2013
