OK, now you are just showing off ;-)
Joking aside, that giant block shows the utility of building regular
expressions from small building blocks.
In any case, I would like to take this opportunity to thank you
for Regexp::Common. It has saved me a lot of work over time.
The OP would benefit from using
http://search.cpan.org/~abigail/Regexp-Common-2.120/lib/Regexp/Common/URI.pm
as opposed to resigning himself to second or third or nth rate
'solutions'.
Thank you.
Sinan

Hmmm... I'm curious, did you write that manually, or generate it
programmatically? If generated, using what software?
And how many decaseconds does it take a regex compiler to process
that?

I believe in simplicity over perfection. Given these choices:
A. Make a 100% perfect program taking 284 man-hours
B. Make a 97% perfect program taking 5 man-hours
I usually take B.

You can read how it is done by looking at the sources of
Regexp::Common modules. It is very elegant.

Not so much that it matters. You might want to measure performance if
you care so much.

But, of course, using Regexp::Common would have cut that down to 2
minutes for a perfect program.

Ok, will do.

I'll try that.
Ok, I just downloaded Regexp-Common-2.120. Now I have a folder
with a bunch of stuff in it. This may sound like an incredibly
stupid question, but what do I do with it? I've never actually
used a CPAN module before. Any hints a CPAN newbie should be
aware of?

One could start with reading a file called README.
