title: Regex for more than 10 digits in a mixed string?
body: <p>I need to check for users that are putting their id in the wrong input box.</p>
  
  <p>They might enter the id as <code>123-456-789-012</code> or <code>123456789012</code> or some variation so I can't just check for digits. The length of the id varies slightly per user, but is always more than 10 digits. </p>
  
  <p>Valid input is a mix of characters and 0-10 digits.</p>
  
  <p>I've seen a lot of solutions for plain digits, but not mixed text. I tried variations of</p>
  
  <pre><code>(\D*\d){0,10}
  </code></pre>
  
  <p>but that didn't work.</p>
