Re: How can we compare two hashed with each other for case insensitive data?

You could also use Data::Dumper in Terse mode to transform the contents of your array into a string which you can lc and eval to make all contents, including hash keys and values, lower case.

#!/usr/bin/perl
use strict;
use warnings;
use Data::Dumper;

my @array1= (
        {
            'My_ID' => '86091',
            'IP' => '2001:DB8:0:0:0:0:0:0/128'
          },
          {
            'mY_id' => '86091',
            'iP' => '2001:DB8:0:0:0:0:0:0/32'
          }
       );

print Dumper(\@array1);

print "\nCompare with\n";
@array1 = @{lowercase(\@array1)};#Dereference array ref to array
print Dumper(\@array1);

sub lowercase{
    my $orig_aref = shift;
    local $Data::Dumper::Terse = 1; #Eliminate '$VAR1 = '
    my $string = Dumper($orig_aref); #Stringify contents of data struc
+ture
    
    my $arefmod = eval lc($string); #Make all data lower case and eval
+uate
    return $arefmod;
}
