title: Using regex to extract multiple numbers from strings
body: <p>I have a string with two or more numbers. Here are a few examples:</p>
  
  <pre><code>"(1920x1080)"
  " 1920 by 1080"
  "16 : 9"
  </code></pre>
  
  <p>How can I extract <strong>separate</strong> numbers like "1920" and "1080" from it, assuming they will just be separated by one or more non-numeric character(s)?</p>
