Extracting information from XML with jQuery

I can't get the link tag to come through when I'm parsing XML. I've tried several approaches. This is what I'm using now:

$(document).ready(function() {  

        $('#news-feed').each(function(){
         var $container = $(this);
         $container.empty();             
            $.get('blogs.xml', function(data){
  开发者_Python百科       $('entry', data).each(function() {
          var $link = $('<a></a>')
          .attr('href', $('link', this).text())
          .text ($('title', this).text());
          var $headline = $('<h5></h5>').append($link);           
          var author = $(this).find('author').text();
          var pubDate = new Date(
            $('published', this).text());
            var pubMonth = pubDate.getMonth() + 1;
            var pubDay = pubDate.getDate();
            var pubYear = pubDate.getFullYear();
            var $publication = $('<div></div>')
                .addClass('publication-date')
                .text('Posted by ' + author + ' on ' + pubMonth + '/' + pubDay +'/'
                +pubYear);

         $('<div></div>')
           .append($headline, $publication)
           .appendTo($container);

            }); 
});

    });

});

You are retrieving the .text() of the link, but the link tag is self-closing so it has not text.

use $('link', this).attr('href') to extract the url from the href attribute of the link tag.
