title: Ignore spaces between a groups of numbers in regex?
body: <p>Hello I am attempting to read vat  numbers in regex with the country code in front:</p>
  
  <p><code>GB 009 0009 09</code></p>
  
  <p>that they could be formatted as so</p>
  
  <pre><code>GB009000909
  GB 009000909
  GB 0 09 0009 09
  </code></pre>
  
  <p>My current expression is: <code>(GB\d{9}\b|GB\s{1}\d{9}\b)</code></p>
  
  <p>How do i go about keeping it simple and ignoring spaces?</p>
