 * `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…

 *  $current = get_post_meta($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]);}}
