I need to write some code to allow users to specify which of a whole bunch of elements(e.g.512/1024) that they want to view. My idea for how to do this was to have them input a semicolon delimited list, for example:
1-10;25;33;100-250 i tried using this to check to make sure they input a valid list that i can process: ########### foreach ($temp2 = <>) { $list1 = $temp2; if ($list1 =~ /(\s*\d+;)+/g || $list1 =~ /(\s*\d+;)+/g ) { print "yay\n"; }else {print "boo\n";}; #print "...",$list1, "...\n"; } ########### which doesn't work, because as soon as it matches the first time, anything goes. How do i get it check for repetition, even though i don't know how many repetitions there will be. there could be 1,2,3,5, even 10 groupings. so the pattern isns't hard, there has to be a number, then either a '-' or s ';', then repeat or not. the only special case is the first one which could just be a single number, or a number '-'number. I just don't know how to implement it.
