title: VBA RegEx getting String with only Number and Hyphen
body: <p>I have a string with something like<br>
  <code>Bl. 01 - 03</code></p>
  
  <p>I want this to be reduced to only<br>
  <code>01-03</code></p>
  
  <p>Everything other than digits &amp; hyphen should be removed. Any ideas how to do it using <a href="/questions/tagged/regex" class="post-tag" title="show questions tagged 'regex'" rel="tag">regex</a> or any other method?</p>
