I know Perl and I was planning to "get the logic" from the answer and
apply it to the language I'll use. Since the question I was asking is
pretty simple (there is almost no script without bbcode nowadays) it
would be easy to adapt the solution. But since you are not trying to
help but trying to complicate things it was not possible, so far.

You see? You just complicate things. I just want to learn what a
variable is. "It is that simple". But you try to teach me what dynamic
or loosely variables are (You even use the word itself inside the your
definition). And this is the exact problem we are having here, with my
question.

1) How can I make you understand, there won't be any attributes or img
tags or javascript etc. Please stop giving examples of HTML
structures,
2) It won't look like that because _I_ will enter the input,
3) Since I won't use this as a serious application it doesn't matter
whether it is secure or not.
4) You are still talking like I want to parse HTML files, completely.
NO. My problem is different, I just used HTML for this mailing list to
understand the problem, easily. In other words it was just a
demonstration.

You insist not to understand my problem. I just want to match
<p><p></p></p>
properly that's it. No attributes, no img tag, no XML, no XSS attack,
no javascript, no fancy characters. I don't want to write a browser
for christ's sake. And I just want to learn how can this structure be
written in regular expressions. I don't want to use a module, I want
to improve my knowledge of regular expressions.
If it will help, I change my example. How can I match structures like
this:
[block]
this is a block
[block]
this is another block
[/block]
first block ends
[/block]
You see? No HTML. This is a language I invented it has just [block]
and [/block] keywords, nothing else. Sure parsing is a good thing but
it is not necessary for this problem and I want to do it in regexp
way, wait a minute, wasn't that Perl's idiom: "There is more than one
way to do it".
Please don't continue the "you are doing it wrong way" thing, the
discussion is already out of its way! If you don't know how to do this
then please don't speak, if you do, please tell...
