dovrei estrarre del testo dentro questi tag span:

<span id=result_box class="short_text">
<span title="il vecchio e il mare" onmouseover="this.style.backgroundColor='#ebeff9'" onmouseout="this.style.backgroundColor='#fff'">
The Old Man and the Sea
</span>
</span>

con questa non va..

preg_match_all('/<span id=\"result_box\" >(.*?)>\/<\/span>/', $data, $result, PREG_SET_ORDER);

Meglio così

function get_tag($classe,$stringa) 
{ 
$pattern = "#<span id=result_box class=\"".$classe."\">(.*?)</span>#";
preg_match_all($pattern, $stringa, $matches1, PREG_OFFSET_CAPTURE); 
$test_ok = $matches1[1]; 
$test_ok = $test_ok[0][0]; 
//echo var_dump($test_ok);

return strip_tags($test_ok);
unset($test_ok);
}
