regexp problem

[Billy Patton]

I'm using regexp coach to assist me but more heads would be helpful

Here is a sample of the data

dogs,10,cats
dogs,[20,30],cats
dogs,[40,[50,60]],cats

I'm looking to validate input data (above) based on reg expression.
To verify legal input.
Ignore the dogs and cats, its just a filler

I currently have 3 different lines that I would like to combine
\d+,?
\[\d+,\d+\],?
[\d+,\[\d+,\d+\]\],?

Here is what I would like to do but regex coach isn't liking it
(\d+,?|\[\d+,\d+\],?|[\d+,\[\d+,\d+\]\],?)

Since the () allows for grouping, I was hoping the | would or it within
the group.

Most of the time when input involves [] (or () or {}) that must match
(balance) you want to step away from regex and use other options.

I probably would use Parse::RecDescent

Got it,
Had my data wrong in regex coach, When i entered it in a perl script I
got it working, then went back to regex coach and it worked then
Here's what I had.

$x = 'dogs,10,cats';
$y = 'dogs,[20,30],cats';
$z = 'dogs,[40,[50,60]],cats';
$x =~ /^dogs,(\d+,?|\[\d+,\d+\],?|\[\d+,\[\d+,\d+\]\],?),?/;
print "$1\n";
$y =~ /^dogs,(\d+,?|\[\d+,\d+\],?|\[\d+,\[\d+,\d+\]\],?),?/;
print "$1\n";
$z =~ /^dogs,(\d+,?|\[\d+,\d+\],?|\[\d+,\[\d+,\d+\]\],?),?/;
print "$1\n";

If you're trying to validate, and you want any help at all, then you
need to tell us what input is valid (duh). Maybe I'm just cranky
today, but it seems like common sense to include this kind of
information when posing a question like this.

does the input have to start with dogs? does it have to end with cats?
do any numbers in between have to be two digits? do they have to be
multiples of 10? do the square brackets have to be balanced? does
there have to be at least one two digit number? if there's more than
one number does it have to be bracketed? etcetera etcetera etcetera.

sometimes I can't believe people that post questions here are
programmers. programming means, in essence, a methodical, linear,
step-by-step approach to problem solving. 90% of the questions people
ask here are just nonsense and bely total disorganization. I'm always
amazed that their scripts work at all.

yep: cranky. sorry(-ish). hahaha

After typing blow, I noticed that i didn't include my regexp witht he
question The mind sees what it wants
Well cranky
Most of the group wants a limited amount, reduced to the smallest amount
of data. That is what I provided, data and a regexp, not my validation
routines and data. Drastic overkill! The problem resided with
combining 3 regexp's into one.
I did solve the problem and the problem only consisted of the data
between dogs and cats
The main problem was that I didn't know if I could the '|' working
within the (). I use the () for grouping not for capturing
