I do it in another approach. I won't put everything in single line of regex, it would make the code hard to debug in future and limit the capability to expand if needed. 


print "Content-Type: text/html; charset=utf-8\n\n";

my (@arr1) = (
"ldt",
"b05dcc00",
"mny",

my (@arr2) = (

foreach my $line1 (@arr1)
{
  chomp($line1); # clear \n if data is from file
  $line1 =~ s/^\s+//; # remove leading whitespace
