body: <p>I have an array with some info. For example:</p>
  
  <blockquote>
    <p>(writer) &amp;</p>
  </blockquote>
  
  <p>or</p>
  
  <blockquote>
    <p>with (additional dialogue)</p>
  </blockquote>
  
  <p>I want to clean this so I only get the text between the parenthesis () and clear everything else</p>
  
  <p>result:</p>
  
  <blockquote>
    <p>writer</p>
  </blockquote>
  
  <p>or</p>

    <p>additional dialogue</p>
