Loop through only five times on XML Success

Loop through only five times on XML Success

I have my code written that returns a list of all the items from my XML list.  I want to just show the most recent five items based on the <pubDate> which looks like this:

  1. <pubDate>Mon, 08 Apr 2013 15:21:26 GMT</pubDate>
The code that I have that works is this but I don't know how to read the pubDate and only show the 5 most recent items.

  1. <script type="text/javascript">
                $(document).ready(function(){
                    $.ajax({
                        type: "GET",
                        url: "/feeds/rss/news-feed-2/",
                        dataType: "xml",
                        success: function(xml) {
                            $(xml).find('item').each(function(){
                                var title = $(this).find('title').text();
                                var link = $(this).find('link').text();
                                var date = $(this).find('pubDate').text();
                                $('<li></li>').html('<a href="'+link+'">'+title+'</a>').appendTo("#news");
                            });
                        }
                    });
                });
            </script>
