perl split by |

I have a text file and each line looks like below

AAAAAAAAAAAA|BBBBBBBB|CCCCCCC|12/12/2022|12/31/0000|DDDDDDDD|EEEEEE|............|ALKDJFHDKFJ||SADF|SAFD

each line has lot of information about employee and seperated by |
each line has almost like 49 separators.
but i want only 12, 29, 36 th value
so I wrote my perl script as below but it did not work
what is the mistake.

#!/usr/bin/perl

use 5.006;
use strict;
use warnings;
use Pod::Usage;
use Getopt::Long;
use Cwd;
use DateTime;
use DBD::mysql;
use DBI;

my $helpme = 0;
my $man = 0;
my $inputFileName = 'C:\\temp\\test.txt';
my $outputFileName = 'C:\\temp\\output.txt';


GetOptions('help' => \$helpme, 'man' => \$man, 'infile=s' => \$inputFileName, 'outfile=s' => \$outputFileName) or pod2usage(2);

pod2usage(1) if $helpme;
pod2usage(-verbose => 2) if $man;

die "No input file name specified!" if !$inputFileName;
die "No output file name specified!" if !$outputFileName;

open(INFILE, "<", $inputFileName) || die "Could not open input file!";
open(OUTFILE, ">", $outputFileName) || die "Could not open/create output file!";

my @where;
while (<INFILE>) {
    chomp;
   my @fields = split /\s*|\s*/;
   print "$fields[29]\n";
}



close INFILE;
close OUTFILE;

Use an array slice if you only want a subset of the fields.

my @fields = (split /\s*\|\s*/)[12,29,36];
print "$fields[1]\n";

If you were counting your fields beginning at 1 instead of 0, then we'd need to adjust that to this:
my @fields = (split /\s*\|\s*/)[11,28,35];
print "$fields[1]\n";
