I'm using functions.php to strip the auto-generated title attributes from links and have got most to work, but there are still some links that I can't find the right functions to call to strip their title attributes; for example, the links for "Post a Comment," "Recent Posts," and "Archives." Any help would be greatly appreciated.

P.S. I know the title can be suppressed with js, but it's still in the code.

Below is the code I'm currently using in my functions.php:

// Remove title attributes

function remove_title_attributes($input) {
    return preg_replace('/\s*title\s*=\s*(["\']).*?\1/', '', $input);
}
add_filter( 'the_category', 'remove_title_attributes' );
add_filter( 'wp_list_categories', 'remove_title_attributes' );
add_filter( 'get_the_category', 'remove_title_attributes' );
add_filter( 'wp_list_pages', 'remove_title_attributes' );
