title: How to convert the html object to string type?
body: <p>I use jQuery method to get some type of html object:</p>
  <pre><code>var content = $('#cke_ckeditor iframe').contents().find('.cke_show_borders').clone();
  </code></pre>
  <p>Then I want to convert it to <code>string</code> type:</p>
  <pre><code>console.log(content[0].toString());
  </code></pre>
  <p>but the result is:</p>
  <pre><code>[object HTMLBodyElement]
  </code></pre>
  <p>How can I turn it into real string?</p>
  <p>By the way, can I turn the converted html string to the html object?</p>
