I am trying to get the main function from a block of code using regex, I will try to exemplify.

For example:

MORE CODE HERE....

start_func function1

var v1 endvar
var v2 endvar

start_func function2

var v3 endvar

end_func

var v4 endvar

end_func

MORE CODE HERE....

I want to extract this from the example:

start_func function1

var v1 endvar
var v2 endvar

start_func function2

var v3 endvar

end_func

var v4 endvar

end_func

Basically, I am trying to extract everything which is inside of start_func function1 using regex. I tried some combinations in Python like:

re.findall(r"^\s*start_func\s+\w+\s+.*?^\s*end_func\s*$", strin_to_search, re.MULTILINE | re.DOTALL)

but it is getting:

start_func function1

var v1 endvar
var v2 endvar

start_func function2

var v3 endvar

end_func

You can't match nested structures wth Python `re`, you will have to write a parser. – Wiktor Stribiżew Mar 20 '19 at 09:35
or use `regex`'s recursive features, ref. https://stackoverflow.com/questions/26385984/recursive-pattern-in-regex – Sam Mar 20 '19 at 09:39
