How to extract text inside brackets?

Question

Algorithms

There is a structure like this:

"item"
{
"inner-item-1" "value"
"inner-item-2"  "value"
"inner-item-3" "value"
    {
        "subitem-1"
    }
    {
        "subitem-2"
    }
}

How to get all the content inside the curly braces of the "item" element, given that there are many such elements in the file?

Answer 1

SteamDB has a lib for parsing vdf -> https://github.com/SteamDatabase/ValveKeyValue
But I didn't find the docks, either blind or they don't exist. Well, look at the decompiler, what's there like.

Answer 2

find the starting "item" and the parenthesis behind it, remember the position.
declare a variable "counter of brackets" with value = 1
then iterate character by character, counting the number of open brackets, add +1 for each open bracket, subtract for each closed bracket.
when the counter reaches zero - remember the position of the last parenthesis.
take everything between the first and last.
