I'm currently making a widget to take and display items from a feed. I have this working for the most part, but for some reason the data within the tag within the item comes back as empty, but I get the data in the and tags no problem.

feed is and xmlhttp.responseXML object.

var items = feed.getElementsByTagName("item");

for (var i=0; i<10; i++){
    container = document.getElementById('list');
    new_element = document.createElement('li');
    title = items[i].getElementsByTagName("title")[0].firstChild.nodeValue;
    link = items[i].getElementsByTagName("link")[0].firstChild.nodeValue;
    alert(items[i].getElementsByTagName("description")[0].firstChild.nodeValue);
    new_element.innerHTML = "<a href=\""+link+"\">"+title+"</a> ";
    container.insertBefore(new_element, container.firstChild);
}

I have no idea why it wouldn't be working for the tag and would be for the other tags.

Here is an example of the rss feed its trying to parse:

<rss version="2.0" xmlns:dc="http://purl.org/dc/elements/1.1/"> 
  <channel> 
    <title>A title</title> 
    <link>http://linksomehwere</link> 
    <description>The title of the feed</description> 
    <language>en-us</language> 
    <item> 
      <pubDate>Fri, 10 Jul 2009 11:34:49 -0500</pubDate> 
      <title>Awesome Title</title> 
      <link>http://link/to/thing</link> 
      <guid>http://link/to/thing</guid> 
      <description> 
       <![CDATA[
       <p>some html crap</p>
        blah blah balh
        ]]> </description> 
    </item> 
</channel>
</rss>
