title: Regex for not matching a string
body: <p>I have a URL:</p>
  
  <p>/ice-cream/stuff/sandwich/banana</p>
  
  <p>I want to write a regular expression that ONLY matches the URL if these conditions are met:</p>
  
  <ol>
  <li>"ice-cream" is in the URL</li>
  <li>"sandwich" is in the URL and comes after "ice-cream"</li>
  <li>"banana" is NOT in the URL</li>
  </ol>
  
  <p>I tried this:
  ice-cream.<em>sandwich.</em>^[(banana)] as well as many others but haven't found the solution.</p>
  
  <p>Help is appreciate it.</p>
