Can you please give a brief explanation regarding how the above regex works? It seems to use a few constructs I've never seen before and searching Google for regex symbols doesn't work very well. In particular, is enclosing a regex in 'm()', as you have done above, equivalent to enclosing it in '//'? What is the trailing xms doing?
