title: Adding an AND clause to a regex
body: <p>I have this simple regex,</p>
  
  <pre><code>[\d]{1,5}
  </code></pre>
  
  <p>that matches any integer between 0 and 99999.</p>
  
  <p>How would I modify it so that it didn't match 0, but matches 01 and 10, etc?</p>
  
  <p>I know there is a way to do an OR like so...</p>
  
  <pre><code>[\d]{1,5}|[^0]{1}
  </code></pre>
  
  <p>(doesn't make much sense)</p>
  
  <p>There a way to do an AND?</p>
