title: Regex: A-Z characters only
body: <p>Hi guys I have a string for example...</p>
  
  <p>"Afds 1.2 45002"</p>
  
  <p>What I wanted to do using regex is to start from the left, return characters A-Z || a-z until an unmatached is encountered.</p>
  
  <p>So in the example above  I wanted to return "Afds".</p>
  
  <p>Another example</p>
  
  <p>"BCAD 2.11 45099 GHJ"</p>
  
  <p>In this case I just want "BCAD".</p>
  
  <p>Thanks</p>
