title: trying to get content inside cdata tags in xml file using nokogiri
body: <p>I have seen several things on this, but nothing has seemed to work so far.  I am parsing an xml via a url using nokogiri on rails 3 ruby 1.9.2.  </p>
  
  <p>A snippet of the xml looks like this:</p>
  
  <pre><code>&lt;NewsLineText&gt;
    &lt;![CDATA[
    Anna Kendrick is ''obsessed'' with 'Game of Thrones' and loves to cook, particularly     creme brulee.
    ]]&gt;
  &lt;/NewsLineText&gt;
  </code></pre>
  
  <p>I am trying to parse this out to get the text associated with the NewsLineText</p>
  
  <pre><code>r = node.at_xpath('.//newslinetext') if node.at_xpath('.//newslinetext')
  s = node.at_xpath('.//newslinetext').text if node.at_xpath('.//newslinetext')
  t = node.at_xpath('.//newslinetext').content if node.at_xpath('.//newslinetext')
  puts r
  puts s ? if s.blank? 'NOTHING' : s
  puts t ? if t.blank? 'NOTHING' : t
  </code></pre>
  
  <p>What I get in return is </p>
  
  <pre><code>&lt;newslinetext&gt;&lt;/newslinetext&gt;
  NOTHING
  NOTHING
  </code></pre>
  
  <p>So I know my tags are named/spelled correctly to get at the newslinetext data, but the cdata text never shows up.</p>
  
  <p>What do I need to do with nokogiri to get this text?    </p>
