title: java html scrape the facebook way
body: <p>When you post a link to facebook, it shows a small thumbnail and a description of the content of that page.</p>
  
  <p>I know it uses <code>og</code> meta tags in html pages, but sometimes even though these meta tags are not present, facebook manages somehow to get the thumbnail and the description  </p>
  
  <p>Example here : <a href="http://www.lepoint.fr/" rel="nofollow noreferrer">http://www.lepoint.fr/</a> (from <code>description</code> meta tag).</p>
  
  <p><img src="https://i.stack.imgur.com/sIgkd.jpg" alt="enter image description here"></p>
  
  <p>I know there are lots of good java html parsers, but is there an API that deals with all different meta tags to get the thumbnail and description of a given html page ?</p>
