body: <p>I want to know how I can add these attributes to my html tag that gets auto generated by our closed CMS system.</p>
  
  <p>I would like to add to our current html tag:   </p>
  
  <pre><code> &lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt;
  &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt;
  </code></pre>
  
  <p>To this:</p>
  
  <pre><code>    &lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt;
  &lt;html xmlns="http://www.w3.org/1999/xhtml"
        xmlns:og="http://ogp.me/ns#"
        xmlns:fb="http://www.facebook.com/2008/fbml"&gt;
  </code></pre>
  
  <p>Is there any way to do this using JQuery?</p>
