title: Scala XML processing is skipping a value
body: <p>I am trying to develop a rest api in scala that grabs the xml of a couple of rss feeds and then displays them in json. So far I can display them as text, which is fine, but I can't get the author to show up. I am creating a list of the articles (where Article is a case class), and searching the xml to provide the values for the Article class.</p>

    &lt;title&gt;Chinese TV Star Apologizes For Remarks Critical Of Mao&lt;/title&gt;
    &lt;description&gt;Bi Fujian, one of the country's most popular television presenters, recently ran afoul of his employer, state-run CCTV, for a parody song he performed at a private banquet.&lt;/description&gt;

  <p>This is an example of the xml I am parsing. Here is the code I am using to parse it:</p>
  
  <pre><code>def xml = XML.loadString(retrieveArticles("http://www.npr.org/rss/rss.php?id=1007")) ++ XML.loadString(retrieveArticles("http://www.npr.org/rss/rss.php?id=1003")) ++ XML.loadString(retrieveArticles("http://www.npr.org/rss/rss.php?id=1001"))
  
      val articles = (xml \\ "item").foldLeft(List[Article]())((ls,item) =&gt; Article((item \ "title").text,
          (item \ "dc:creator").text,
          (item \ "pubDate").text,
          (item \ "link").text,
          (item \ "description").text) :: ls)
  </code></pre>
  
  <p>All of the other values are being processed correctly. Author is the only value that is not showing up. When I call the api to show the articles, this is what I get:</p>

  <p>Why is the author not being shown when all of the other values are displayed with no problems?</p>
