title: Regex not operator
body: <p>I need to use a regex to pull a value out a url domain that will exclude everything but the host (ex: wordpress) and domain type (ex .com). The urls are dynamic and contain 2-3 values for each result (www.example.com or example.org). I am trying to use this expression, but I am only getting back the first letter of every item I am attempting to exclude:</p>
  
  <p><strong>Expresssion</strong></p>
  
  <pre><code>(?!wordpress|com|www)(\w+|\d+)
  </code></pre>
  
  <p><strong>String</strong></p>
  
  <blockquote>
    <p>example.wordpress.com</p>
  </blockquote>
  
  <p><strong>Results</strong></p>
  
  <ol>
  <li>example </li>
  <li>ordpress</li>
  <li>om</li>
  <li>Desired Result</li>
  </ol>
  
  <p>example</p>
  
  <p>Any assistance would be greatly appreciated</p>
