Nested tags Can't Post
Hi, I want to take a string like

Code
 one 
Quote
 two 
Quote
 three bold
 four

and end up with

Code
  
 
one [someText] four [someText] six

but everything i tried so far with regex either stops and the first closing
 tag, or starts with the last opening
Quote
tag :(

how can I do this?

oops, sorry, i didn't realize it will interpret my tags inside CODE tag, many forum engines dont'...

i basically need to convert

start [tag] text inside [tag] text inside nexted tag [/tag] more text [/tag] middle [tag] tagged text [/tag] the end

to

start [description] middle [description] the end

I am not good with psuedo data, are those HTML tags or something else? Can you post an example of the real data?

Re: [KevinR] Nested tags [In reply to] Can't Post
i did in the first post :) -- its BB codes. basically chage TAG to QUOTE in my last post (this board renders it, so i can't post it here) - that is real example, and "[description]" can be any text, i use "
Quote
", but it could be "*qote*", "QUOTE", "=anytext=", ... whatever.

i'm listing latest posts (subject + first 200 chars) from my phpBB forum on my home page, and strip BB tags from it, but when people replying to a quote i want to indicate that there is a quote. of course people keep hitting "quote" button creating nested quotes, some of them 4-5 levels deep. i don't what to just strip quote tags and leave quote's text cause first 200 chars will the the text of the quote almost always, and on the from page i'll have the list of the same replys :-/

obviously this isn't very important project :) but i'm just very curious cause I can't find a solution with regex (im not very good at it too :)). i could probably do something without regex, with loops, counting levels, but I can't believe its not possible with regex..

thanks

It might be possible with just using a regexp, but it sounds like the wrong tool for the job. Besides, since you are using a php powered BB I am not sure why you aasking on a perl forum. I would ask on a forum dedicated to that particular bulletin board. Maybe someone has already done something similar.

my website is not on php, only the forum is. and everything similar that already exists (from what i found) only displays titles/subjects or simply strips tags from the body.
