title: extract word with regular expression
body: <p>I have a string <code>1/temperatoA,2/CelcieusB!23/33/44,55/66/77</code> and I would like to extract the words <code>temperatoA</code> and <code>CelcieusB</code>. </p>
  
  <p>I have this regular expression <code>(\d+/(\w+),?)*!</code> but I only get the match <code>1/temperatoA,2/CelcieusB!</code></p>
  
  <p>Why?</p>
