Re: Key value pair in hash inside while loop

[neilwatson]

You did not clearly specify actual and desired results. But, this may get you started.

#!/usr/bin/perl

use strict;
use warnings;
use feature 'say';
use Data::Dumper;

my %hash;

for my $line (<DATA>)
{
    chomp $line;
    next if ($line =~ /dG\s=\s(.*?)\s/);

    my @temp = split(/\s+/, $line);
    $hash{ $temp[1] } = $temp[4];
}

say Dumper( \%hash );
