Do you mean something like:
use strict;
use warnings;
my $my_input = 'xxxc=2&xxx1=val1&xxx2=val2';
my @fv_pairs = split /\&/ , $my_input;
my %INPUT;
foreach (@fv_pairs) {
my ($field, $value) = split /=/, $_, 2;
next unless defined $value;
$value =~ s/\+/ /g;
$value =~ s/%(\dA-Fa-f{2})/pack("C", hex($1))/eg;
$INPUT{$field}=$value;
}
print join "\n", map {"$_ => $INPUT{$_}"} sort keys %INPUT;
Prints:
xxx1 => val1
xxx2 => val2
xxxc => 2
