RegExp issue preg_match_all

[rlemon]

<?
$html = file_get_contents("http://en.wikipedia.org/wiki/Wikipedia:Featured_articles");
$pattern = '(\<span class\=\"featured\_article\_metadata has\_been\_on\_main\_page\"\>\<a href\=\").*([\w]+)(\" title\=\".*[\w]+\"\>.*[\w]+\<\/a\>\<\/span\>)';
$outputArray = preg_match_all($pattern,$html,$matches);
print_r($matches)
?>


i run this and receive


Warning: preg_match_all(): Unknown modifier '.' in /home/www/roblem.100webspace.net/Wiki.php on line 4
Array ( )


Any ideas?

i need to pull things from the wikipedia page for personal use but am too lazey too do it by hand, if you were wondering why i'm doing this.

try this regexp.

$outputArray = preg_match_all('/(?<=<span class="featured_article_metadata has_been_on_main_page">).*?(?=<\/span)/is', $html, $matches);
