  </code></pre>
  
  <p>I can get all the information from <code>article-additional-info</code> class to which the above-mentioned piece of code belong. I can do it by using <code>document.getElementsByClassName("article-additional-info")[0].innerText</code>.</p>
  
  <p>How do get individual information such as: <code>Author(s):</code>?
  I'd like to avoid using RegEx.</p>
