Hi have this function that is meant to return all the post of category news, the problem is that is only returning one post of that category I want to return all the post.

PHP Code:
<?php
//function to display the third last news published
function wptuts_third_last_news_shortcode($atts$content=null) {
query_posts'category_name=news' );   if (have_posts()) :
      while (
have_posts()) : the_post();
              
$blog_link get_permalink(); // this si the link
         
$return_string =  "<a href=" .$blog_link .">" get_the_title() . "</a>" ;
      endwhile;
   endif;
   
wp_reset_query();
   return 
$return_string;
}
add_shortcode'third_last_news''wptuts_third_last_news_shortcode');
?>
