I have no idea how to do this ..
str = '[a,b,c,d,e,[f1,f2],g],[u,v,w,[x1,x2],[y1,y2],z]';
Using this code:
regexp(str,'\[.*?(\[.*?\],[.*?\]).*?\]','tokens');
i got an answer like this:
ans =[f1,f2],g],[u,v,w,[x1,x2]
but what I want is like this:
ans = [x1,x2],[y1,y2]

That doesn't really answer the question. I showed you how to find the answer you requested, then I asked you to give the general form, including the rule for finding what you want. "The string is dynamic" tells me nothing really. Good luck.

Remember, .* will match everything including [ or ] characters. You need to exclude those characters from the search if you are looking for the ] matching a [ .

I have tried this but it doesn't work:
ans = regexp(str,'\[.*?\[[^\]]*?\].*?\]','match')
