If you can "cheat" and use the whitespace to match items then here's
my ugly hack:

$items = preg_split('/^ <li>/m',$menu);
$out_ar = array();
foreach($items as $item)
{
    $out_ar[] = strstr($item,'<strong>') ? $item :
preg_replace('/<\/a>.*/s',"</a></li>\n",$item);
}


echo implode('  <li>',$out_ar) . '</ul>'
