title: Reading text in `<![CDATA[...]]>` with SimpleXMLElement
body: <p>I'm importing an RSS feed with <code>SimpleXMLElement</code> in PHP. I'm having trouble with the title and description. For some reason, the website I get the feed from puts the title and description in <code>&lt;![CDATA[...]]&gt;</code>:</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;item&gt;
  &lt;title&gt;&lt;![CDATA[...title...]]&gt;&lt;/title&gt;
  &lt;link&gt;...url...&lt;/link&gt;
  &lt;description&gt;&lt;![CDATA[...title...]]&gt;&lt;/description&gt;
  &lt;pubDate&gt;...date...&lt;/pubDate&gt;
  &lt;guid&gt;...link...&lt;/guid&gt;
  &lt;/item&gt;
  </code></pre>
  
  <p>When I do a <code>var_dump()</code> on the SimpleXMLElement, I get (for this part):</p>
  
  <pre class="lang-js prettyprint-override"><code>  [2]=&gt;
    object(SimpleXMLElement)#5 (5) {
      ["title"]=&gt;
      object(SimpleXMLElement)#18 (0) {
      }
      ["link"]=&gt;
      string(95) "...link..."
      ["description"]=&gt;
      object(SimpleXMLElement)#19 (0) {
      }
      ["pubDate"]=&gt;
      string(31) "...date..."
      ["guid"]=&gt;
      string(48) "...link..."
    }
  </code></pre>
  
  <p>How can I get the value <em>in</em> <code>&lt;![CDATA[...]]&gt;</code> to read the title and description from the feed?</p>
