이것은 json 형식의 텍스트입니다. 모든 것이 제대로오고 있지만, long_description 정규식 작동하지 않는 이유를 모르겠어요

my ($title)=$text=~/"title"\s*:\s*"(.*?)"\s*,\s*"/is;** 
my ($long_des)=$text=~/"long_description"\s*:\s*"(.*?)"\s*,\s*"/is; 

, 나는 빈을 얻을 : 나는이 정규식을 사용하고 같은

short_description로하고 long_description 특정 필드를 추출합니다 끈. 이 문제를 해결하려면 무엇을해야합니까?

Answer 1

나는 한 걸음 뒤로 물러나라고 제안 할 것이다. JSON의 상황에 따라 JSON을 정규식으로 해킹하는 것은 불쾌합니다. 정규 표현식은 상황에 맞는 것이 아니므로 항상 해킹 된 해결책입니다. 당신이 JSON을 구문 분석하는 경우

#!/usr/bin/env perl

use warnings; 
use Data::Dumper; 
use JSON;
