Improving the Post Excerpt function

hey guys,
I’ve recently found a great way to improve the default post excerpt function with a little code added to my functions.php

function improved_trim_excerpt($text) {
	global $post;
	if ( '' == $text ) {
		$text = get_the_content('');
		$text = apply_filters('the_content', $text);
		$text = str_replace(']]>', ']]>', $text);
		$text = preg_replace('@<script[^>]*?>.*?</script>@si', '', $text);
		$text = strip_tags($text, '<p>');
		$excerpt_length = 40;
		$words = explode(' ', $text, $excerpt_length + 1);
		if (count($words)> $excerpt_length) {
			array_pop($words);
			array_push($words, '[...]');
			$text = implode(' ', $words);
		}
	}
	return $text;
}

and also unloading the default function and loading the new one with

remove_filter('get_the_excerpt', 'wp_trim_excerpt');
add_filter('get_the_excerpt', 'improved_trim_excerpt');

it works great now, since it won’t remove any html codes from the post, so it respects the new lines I’m adding to the post.

my question is the following…is there a way to make it add everything before the first line break? so it displays the post, but when it reaches the first new line, it stops ? hope you understand ??

thanks in advance,
