I'd use Tie::File and set the record separator. Then use some multiline regexes. I tested your data out on the following code, and it worked like a charm. 
use strict;
use warnings;

use Tie::File;

my ($record, @array, %data) = (0);
my $file = 'whatever';

tie @array, 'Tie::File', $file, recsep => '=' x 30 . "\n";

while ($array[$record]) {
    $record++, next unless $array[$record] =~ m/^[^=]/;
    @{$data{$record}}{'primary', 'level', 'group', 'id_node',
                    'inverse', 'secondaries'} =
        $array[$record] =~ m/# get primary id, level, and group
                             Primary[^:]+ \D+(\d+) \D+(\d+) \D+(\d+)

                             # then the id-node and inverse
                             (?:[^:]+:){4} \D+(\w+) \D+(\d+)

                             # skip 'Secondary ID' line
                             [^K]+

                             # and grab the rest until end of record
                             ([^=]+)
                            /gxms;
    $record++;
}

for my $rec (keys %data) {
    for (keys %{$data{$rec}} ) {
        print $_ . ' is set to ' . $data{$rec}{$_} . "\n";
    }
}
