title: Parse classname for number at end?
body: <p>I have elements. I know for sure they will have a class 'fc-id#' where '#' is a number.</p>
  
  <p>I need to somehow get that number. This will always be the first class of the element.</p>
  
  <p>Is there some way to get the number at the end?</p>
  
  <p>Thanks</p>
