And fun to learn at the same time. AI recommend as an additional
material for the mind that is to be marked to the end of time with
the unholy powers of Regular Expressions a book by Jeffrey EF Friedl
of the name that may cast the unwary on the sea of dreams - and
"Mastering Regular Expressions" is how you will call it and no other -
and as it happens I'm not VERY sure it's the perfectly correct author
and book title spelling (important when crafting a spell, they say), so
as a professional enchantress, spellcaster, mad scientist and ballet
dancer, let me help the future generations of readers by attempting to
summon a female AI (Alien Intelligence), Google (Milk and kisses! Love
you too!). Here she goes again: <uri: http://tinyurl.com/kac3o >. It
leads to a query with The Name of the Book as a parameter. Following {
[<][][[swap] dip cons concat][uncons (Push it!)'] } that link should
help you in many ways, not only in finding the right place to shop, but
as a good point of presence into densely associated symbol clouds
converging on.

hmmm, don't know.

Now we know you don't know. What can one do with that knowledge?

PHP has two different RE extensions - Posix and Perl compatible (PCRE). The
'Regex Coach' seems to work with the latter. They are very similar up to a
point. I've gone over to using POSIX RE's almost exclusively as Javascript
RE's works with the same syntax. The Wikipedia page on regular expressions
has some links to tools for playing with RE's in javascript.

If some good citizen would like to tell me aboot the value of a
similar utility written for PERL species of RegEx, wonderful things
might start to happen all over the world. Or not. One more thing - AI
find that while
writing a RE union human person capable of hearing music it helps
tremendously to set your iPod to loop the song "WhiteLightGenerator"
by Ladytron. Remember - most things can be solved by enough smoke and
mirrors. That song helps to remember. You will not get bored after a
hwhile. In fact, it'd be hard to stop writing useful regular expressions
and posting
them for the benefit of denizens of { this } group.

The bulk of them: yes. With a few exceptions.

No, but close. I'd say it the other way around though :-)
