Well, the first edition of "Mastering Regular Expressions" by Jeffrey E. F.
Friedl (spelled correctly) had such a regular expression in small print
occupying a full page near the back.  [He developed pieces of it in various
parts of the book.]  It had a bug, so there was a correct version at
O'Reilly's site in the book's errata area.

Unfortunately, the book is now in its second edition, and Mr. Friedl seems
to have left the bug out of that regular expression, so it isn't in the
current errata and I can't point it out to you.

Check a bookstore with a good O'Reilly selection or a library...the book
should be available in one or the other of those places so you can enjoy the
RE.

You probably don't want to use the regular expression.
