Hello,

i have the following Situation: a String of Numbers is given, an Array for matching several Numbers is given, i need to cut the matching Number and then print both the mathing Number and the rest with a ; between.

it shoud match from the beginning and it shoud match the longes possibility

Example: this number is given 012345666666 , these matchings are given 012345 and 0123456 , then 0123456 shoud be returnt not 012345

the array itself is 5025 elements big and i'm searching for faster ways then to join the array and doing a regex on each element.

also i can't find a way that the regex deliver back the longest matching possibility, for this reason i sortet the array so that the longest numbers comes first

my $filterregex = join('|',@Numbers)
/^$filterregex/

i'am using the Regex vars matching and rest to get everything i need, but the regex is still not working correctly and it's not that fast.

Summary: regex needed that matches from the beginning and delivers just the longes matching value, a possible faster way woud be great
