Correction: That should be [a-z0-9]+. (note the plus) -----Original Message----- From: Timothy Johnson To: 'Alex Cheung Tin Ka '; '[EMAIL PROTECTED] ' Sent: 11/13/02 12:01 AM Subject: RE: match only a-z or 0-9
You've essentially already done it. [a-z0-9] is a character class that includes all characters within that range. So something like this would work: if($string =~ /^[a-z0-9]$/){ print "It's only letters and digits.\n"; }else{ print "There's something else in there.\n"; } -----Original Message----- From: Alex Cheung Tin Ka To: [EMAIL PROTECTED] Sent: 11/12/02 11:14 PM Subject: match only a-z or 0-9 Dear All, Could anyone tell me how to make a regular expression for match a string only [a-z0-9] ?
