title: Search text with a regular expression to match outside specific characters
body: <p>I have text that looks like:</p>
  
  <blockquote>
    <p>My name is (Richard) and I cannot do
    [whatever (Jack) can't do] and
    (Robert) is the same way [unlike
    (Betty)] thanks (Jill)</p>
  </blockquote>
  
  <p>The goal is to search using a <strong>regular expression</strong> to find all parenthesized names that occur anywhere in the text BUT in-between any brackets.</p>
  
  <p>So in the text above, the result I am looking for is:</p>
  
  <ul>
  <li>Richard</li>
  <li>Robert</li>
  <li>Jill</li>
  </ul>
