title: I need a regular expression to insert some code at the beginning of each line in Webuilder
body: <p>I'm using Webuilder to do all my coding and I run into a tedious task,
  I need to insert some repetitive code at the start of each line and I thought maybe, this can be done using a regex...
  But, I'm using Webuilder and can't seem to get it to work, I looked at several alike questions but none provided the answer. </p>
  
  <p>Any idea on how to accomplish this?</p>
