Regular Expression Challenge

Hi, I am trying to pull out the following information via a regular expression. The string I am searching on is 'wed-thurs 9:35, 14:56, 18:35' and I want it to retreive wed thurs 9:35 14:56 18:35 The regular expression I am using is ([a-z]+)-([a-z]+) +([0-9]{1,2}:?[0-9]{0,2})[, ]* It seems to be grabbing the wed thurs 9:35 but I can't seem to retrieve the rest of the times. Anyone have any ideas? BTW There can be any number of 'times' in the string and also the 'times' can be with or without the colon and the minutes, hence the '}:?[0-9]{0,2}' part of the regexp.
