   function updatelink($id) {

   preg_match('#See the link <a href=(.*)>#', $_POST['content'], $rect);

   $current = get_post_meta($id, 'link');

   if (!isset($current) || (sizeof($current)==0)) {
add_post_meta($id, 'link', $rect[1]);
}
else {
update_post_meta($id, 'link', $rect[1]);
}
}

   add_action('save_post', 'updatersslink');

   i would capture a link when post is saved....but the preg match didn't work good.

   if i use in preg_match "a href=(.*)>" i capture the link with \"...if i use "a href=\"(.*)\">" the script doesn't capture anything...

   Now it works, how can i return the content of the meta data in the wp loop, i try to use return in the bottom of the function but did'nt return anything....

   function updatersslink() {

   global $post;

   preg_match('#Original link <a href="(.*)">#', $post->post_content, $rect);

   $current = get_post_meta($post->ID, 'rsslink');

   if (!isset($current) || (sizeof($current)==0)) {
   add_post_meta($post->ID, 'rsslink', $rect[1]);
   }
   else {
   update_post_meta($post->ID, 'rsslink', $rect[1]);
   }
   }

   return 'sda79fa7fdfa95taf' ;

   ?>
