title: Ignoring white space for a Regex match
body: <p>I need to match 8 or more digits, the sequence of which can include spaces.</p>
  
  <p>for example, all of the below would be valid matches.</p>
  
  <pre><code>12345678
  1 2345678
  12 3 45678
  1234 5678
  12 34567 8
  1 2 3 4 5 6 7 8
  </code></pre>
  
  <p>At the moment I have <code>\d{8,}</code> but this will only capture a solid block of 8 or more digits.<br>
  <code>[\d\s]{8,}</code> will not work as I don't want white space to contribute to the count of chars captured.</p>
