breadcrumbs for tags?

hey guys, i’m using the following code to have breadcrumbs on my website. however i wonder how i can view a breadcrumb for a tag as well. now it only is shown for single-pages and categories but not for tags.

if (!is_home()) {
		echo " » ";
		if (is_category() || is_single()) {
			the_category('title_li=');
			if (is_single()) {
				echo " » ";
				the_title();
			}
		} elseif (is_page()) {
			echo the_title();
		}
	}

thank you for your help!
