in thread Regex only the longes Value , and possible speedup Problem

hi grandfather,

1. normaly not but it can happen so i load these elements from a file and read it into an array
2. yes they do everytime
3. can be 1 can be 500000
4. the minnimum matching is 4 numbers , the maximum i don't know but i never see everything larger then 14 so 20 shoud be the max
6. im loking for a single best match

here is some sample data for the array
__Array_DATA__ 4930 49201 49202 49203 492041 492043 492045 492051 492052 492053 492054 492056 492058 492064 492065 492066 49208 49209 492102 492103 492104

here are some strings
4920911223344 492065577883667 49206656672

the result for these strings shoud look like
49209;11223344 492065;577883667 492066;56672

finaly my testing code wich is far from greatness ;)
use strict; use warnings; use File::Spec; open(my $fh_in, '<', 'Script\\onkz.txt') or die("open failed: $!"); open(INFILE, '<', 'data.txt') or die("open failed: $!"); my @ONKZ = <$fh_in>; my $filterregex = join('|',@ONKZ); while (<INFILE>) { if($_ =~ /^($filterregex)/){ print "$&;$'\n"; } }
