body: <p>How to check for empty text from a rich text editor?</p>
  
  <p>I have a Rich text, similar to this one where I am typing. </p>
  
  <p>By default, the value is set to <code>&lt;br&gt;</code> so, in Java when i check for <code>request.getParameter("desc");</code> I will get the value as <code>&lt;br&gt;</code> </p>
  
  <p>I want to check for empty string, including any html tags like just <code>&lt;br&gt;&lt;hr&gt;</code> etc</p>
  
  <p>Is this possible?</p>
