正则表达式，提取括号之间的值

Question

example:

"today  [(["hi"],{"my"})],["ok"],("good")),(["gg"],["fire"])] nice game [(["1"],{"2"})],["3"],("4")),(["5"],["6"])] end."

->

[(["hi"],{"my"})],["ok"],("good")),(["gg"],["fire"])]
[(["1"],{"2"})],["3"],("4")),(["5"],["6"])]

In this case, there is a noise in the middle.

It doesn't work in the usual way

Please give me an idea of extracting the value between parentheses in another way

Answer 1

I love regex, almost as much as I hate them. Writing an effective regex can take a problem from impossible to trivial.

Knowing how to iterate one is very important. Let me teach a man to fish.

Consider using an online regex tool: https://regex101.com/

Input your string:

Then try to Match it. I did with the following \([^()]+\)

That is:

1. escape the parenthesis you want to match on \( and \) because they are special symbols.
2. You know you want to match everything that isn't a parenthesis between them. So I use a no-match clause by doing [^...] where the elipsis are all the characters I don't want to match. I then add my parenthesis raw in there [^()]
3. Finally. I want to have 1 or more of those so I use + .

Thus I have my awnser.
