Sorry, I flipped a bit. Look at the source for strip_shortcodes. It
gets the regex pattern from get_shortcode_regex(). You can use that in
preg_replace. Something like this extempore and untested snippet:

$pattern = get_shortcode_regex();
$pattern = str_replace('(.?)', '', $pattern);
$pattern = str_replace('2', '3', $pattern);
$content = $post->post_content;
$shortcodes = preg_replace("/.*($pattern).*?/s", '$1', $content);
