title: How to write a twitter regex expression?
body: <p>I need a twitter expression: </p>
  
  <pre><code>twitter.com\/[\w\/\.=-]*
  </code></pre>
  
  <p>This one works fine, except it does capture generic twitter widgets.js library</p>
  
  <p>I would like to capture ALL twitter.com <strong>EXCEPT those who cantain "widgets.js"</strong> (using regex)</p>
  
  <p>ex: </p>
  
  <pre><code>twitter.com/myaccount: GOOD
  twitter.com/JohnDOes: GOOD
  twitter.com/widgets.js: BAD
  </code></pre>
  
  <p>Regards</p>
