regex - C++ regexp to parsing nested struct -
i have string formatted follows permanent way: { first nested string; { second nested string; } } nesting may arbitrary depth. each sub-element formatted closing brace, adding 2 spaces previous level of nesting , closing brace. want receive regular expression allows obtain nested data. example, above example result should be: first nested string; { second nested string; } i wrote following code allows parse strings in 1 line, symbol '.' character except newline. regex regex("\\s*\\{\\s*(.*?)\\s*\\}\\s*"); string testinput = "{\n" " first nested string;\n" " {\n" " second nested string;\n" " }\n" "}\n"; smatch match; if (regex_search(testinput, match, regex)) { auto result = match[1].str(); } what regular expression make can receive nested data? in advance. the regex implementation c++ standard library not support recursion, needed match nested structures. like
