如何在C++中解析逗号分隔的字符串，其中一些元素用逗号引起来？

#include <iostream>
#include <sstream>
#include <vector>

int main() {
    std::string input = "element1,element2,'element3,with,commas',element4";
    std::vector<std::string> elements;
    std::stringstream ss(input);
    std::string item;

    while (std::getline(ss, item, ',')) {
        elements.push_back(item);
    }

    // 输出解析后的元素
    for (const auto& element : elements) {
        std::cout << element << std::endl;
    }

    return 0;
}

#include <iostream>
#include <sstream>
#include <vector>

int main() {
    std::string input = "element1,element2,'element3,with,commas',element4";
    std::vector<std::string> elements;
    std::stringstream ss(input);
    std::string item;

    while (std::getline(ss, item, ',')) {
        if (item.front() == '\'' && item.back() != '\'') {
            // 引号未闭合，继续读取直到闭合
            std::string temp;
            while (std::getline(ss, temp, ',')) {
                item += ',' + temp;
                if (temp.back() == '\'') {
                    break;
                }
            }
        }
        elements.push_back(item);
    }

    // 输出解析后的元素
    for (const auto& element : elements) {
        std::cout << element << std::endl;
    }

    return 0;
}
