I would suggest a slightly different approach:

Create a Plugin for Hook admin_global (not attached to the product, only for the dev machine!)

PHP Code:

function adminhelp_xml_handler($xml)
{
    global $product_details, $vbulletin;
    if ($product_details)
    {
        // query topics
        $helptopics = array();
        $topics = $vbulletin->db->query_read("
            SELECT * FROM " . TABLE_PREFIX . "adminhelp
            WHERE volatile = 1
                AND (product = '" . $vbulletin->db->escape_string($product_details['productid']) . "')
            ORDER BY action, displayorder
        ");
        while ($topic = $vbulletin->db->fetch_array($topics))
        {
            $helptopics["$topic[script]"][] = $topic;
        }
        unset($topic);
        $vbulletin->db->free_result($topics);

        require_once(DIR . '/includes/class_xml.php');
        $adminhelp_xml = new XMLexporter();

        $adminhelp_xml->add_group('helptopics', array('product' => $product_details['productid']));

        ksort($helptopics);
        foreach($helptopics AS $script => $scripttopics)
        {
            $adminhelp_xml->add_group('helpscript', array('name' => $script));
            foreach($scripttopics AS $topic)
            {
                $attr = array('disp' => $topic['displayorder']);
                if ($topic['action'])
                {
                    $attr['act'] = $topic['action'];
                }
                if ($topic['optionname'])
                {
                    $attr['opt'] = $topic['optionname'];
                }
                $adminhelp_xml->add_tag('helptopic', '', $attr);
            }
            $adminhelp_xml->close_group();
        }
        $adminhelp_xml->close_group();

        $xmloutput = str_replace("\n</product>", "\n\t" . substr(str_replace("\n", "\n\t", $adminhelp_xml->output()), 0, -1) . "</product>", $xml);
        header('Content-Length: ' . strlen($xmloutput));
        return $xmloutput;
    }
    else
    {
        return $xml;
    }
}


if ($_REQUEST['do'] == 'productexport')
{
    ob_start('adminhelp_xml_handler');
} 


When creating your product, include the following as part of your install code

PHP Code:

preg_match('/(\t<helptopics.*<\/helptopics>)/s', $xml, $matches);
require_once(DIR . '/includes/adminfunctions_help.php');
$adminhelp = $matches[0];
xml_import_help_topics($adminhelp); 


Done. No phpMyAdmin, manual importing or whatever
