title: Regex: Matching 4-Digits within words
body: <p>I have a body of text I'm looking to pull repeat sets of 4-digit numbers out from.</p>
  
  <p>For Example:</p>
  
  <blockquote>
    <p>The first is 1234 2) The Second is 2098 3) The Third is 3213</p>
  </blockquote>
  
  <p>Now I know i'm able to get the first set of digits out by simply using:</p>
  
  <pre><code>    /\d{4}/
  </code></pre>
  
  <p>...returning 1234</p>
  
  <p>But how do I match the second set of digits, or the third, and so on...?</p>
  
  <p>edit: How do i return 2098, or 3213</p>
