Need Regex Tutorial

[Tim Johnson <tim@johnsons-web.com>]

My last postings have indicate to me that I need to roll up my sleeves
and learn regex from the ground up.

1)Info on my GNU emacs *does not* show anything about regular
  expressions. Info on my XEmacs does and it is not sufficient for me.

  I would appreciate pointers to online docs on regex, since
  my emacs does appear not have them.

2)I'm an old dog, but I *can* learn new tricks if I have examples.
  *lots* of examples, starting with the most basic. I can work from the
  Fiedl book, but seeing some basic emacs examples will help me to
  reconcile the differences between emacs regex (or as Friedl calls 'em -
  'scattered toothpicks') and "classic" approaches 
 
  Pointers to examples welcome.

  thanks
  tim
