  <p>Please note:</p>
  
  <ol>
  <li>The string is in one line and you could notice that in each {} pair, the content is very similar.</li>
  <li><strong>I could only do it with regex</strong> and cannot do any split by any functions. </li>
  <li>I want to use regular expression to filter out the one containing CustomerID with minimum complete length. For example, I want to filter out as below.</li>
  </ol>

  <p>But I'm not sure how to do this. I tried many times with zero width assertion but still cannot figure it out. Could you please enlighten me? Thanks!</p>
