title: Using regex to convert hex to ascii
body: <p>I try to work on a translator, in Java, that use regex for configuring it. </p>
  
  <p>I have the following hex string :
  31353333303430353431455232335445303031</p>
  
  <p>and I must convert it and find ascii string like this :
  1533040541ER23TE001</p>
  
  <p>My question is can I use regex to convert an hex string to an ascii string.</p>
