Hi, you should dump $doc with something like Data::Dumper: 
$VAR1 = {
    'document' => {
        '\\2006\\200601\\20060125\\20060125_19.txt' => {
            'record' => [
                {
                    'group'           => 'P6',
                    'data-class'      => 'Target',
                    'sentence-number' => '3'
                },
                {
                    'group'           => 'P6',
                    'data-class'      => 'Good',
                    'sentence-number' => '12'
                }
            ],
            'sourcecategory' => 'News Archive',
            'datetime'       => '2006/01/25',
            'schemeversion'  => '1.1'
        },
        '\\2006\\200601\\20060125\\20060125_18.txt' => {
            'sourcecategory' => 'News Archive',
            'datetime'       => '2006/01/25',
            'schemeversion'  => '1.1'
        }
    }
};

As you can see, the records are an array ref of hashrefs at the same level as the documents attributes ($doc->{document}->{$key}->{record}). You can iterate over the records at this point (i.e. check if record is defined and is an arrayref).
