Здравствуйте!
Есть такой код, который из страницы должен подёргать все строки между тегами <td></td>:

PHP:
скопировать код в буфер обмена

 
<?PHP 
            $url = "http://www.bg-samara.ru/catalog.html";
            $html = file_get_contents($url);
            $exp = '"\\n\\t*"';
            // удаляем символы перевода строки и табы
            $returnValue = preg_replace($exp, '', $html);
            $returnValue = preg_replace("<br />", '', $returnValue);
            
            // выбирает то, что интересует
            $exp = '/(?<=\<td\>)([а-яА-Яa-zA-Z0-9\.\,\s\(\)\/]*)(?=\<\/td\>)/';
            preg_match_all($exp, $returnValue, $matches);
            print_r ($matches);
?>
 

Что есть на странице (небольшой кусок):

Спойлер (Отобразить)

Что выводит программа:

выбирается из страницы не всё что мне нужно. Видно, что не выводятся, как минимум, названия районов. Почему?

А если так?

PHP:
скопировать код в буфер обмена

  $exp = '/(?<=\<td\>)([а-яА-Яa-zA-Z0-9\.\,\s\(\)\/]*)(?=\<\/td\>)/ui';
