我在一个数组中有两个元素。

"3a49c9bb-caaf-48d8-b77c-45161cdf8ff5,Stadtwerke Feldkirch,AT006110,\"Verteilernetzbetreiber,Strom\",http://www.stadtwerke-feldkirch.at ,,,2023-02-13T16:05:03.452Z,2023-02-13T16:05:03.452Z\r"

"a601f77b-c7ed-40a8-a639-9baa25ca28a5,Revertera'sches Elektrizitätswerk,AT003540,\"Verteilernetzbetreiber,Strom\",http://www.revertera.at ,,,2023-02-13T16:05:03.492Z,2023-02-13T16:05:03.492Z\r"

有效CSV字符串中的第一个元素，但第二个不是，我不知道为什么。
我使用这个函数将字符串转换为数组：

const data = ["3a49c9bb-caaf-48d8-b77c-45161cdf8ff5,Stadtwerke Feldkirch,AT006110,\"Verteilernetzbetreiber,Strom\",http://www.stadtwerke-feldkirch.at ,,,2023-02-13T16:05:03.452Z,2023-02-13T16:05:03.452Z\r", "a601f77b-c7ed-40a8-a639-9baa25ca28a5,Revertera'sches Elektrizitätswerk,AT003540,\"Verteilernetzbetreiber,Strom\",http://www.revertera.at ,,,2023-02-13T16:05:03.492Z,2023-02-13T16:05:03.492Z\r"];

function CSVtoArray(text) {
    var re_valid = /^\s*(?:'[^'\\]*(?:\\[\S\s][^'\\]*)*'|"[^"\\]*(?:\\[\S\s][^"\\]*)*"|[^,'"\s\\]*(?:\s+[^,'"\s\\]+)*)\s*(?:,\s*(?:'[^'\\]*(?:\\[\S\s][^'\\]*)*'|"[^"\\]*(?:\\[\S\s][^"\\]*)*"|[^,'"\s\\]*(?:\s+[^,'"\s\\]+)*)\s*)*$/;
    var re_value = /(?!\s*$)\s*(?:'([^'\\]*(?:\\[\S\s][^'\\]*)*)'|"([^"\\]*(?:\\[\S\s][^"\\]*)*)"|([^,'"\s\\]*(?:\s+[^,'"\s\\]+)*))\s*(?:,|$)/g;
    // Return NULL if input string is not well formed CSV string.
    if (!re_valid.test(text)) return null
    var a = []; // Initialize array to receive values.
    text.replace(re_value, // "Walk" the string using replace with callback.
        function(m0, m1, m2, m3) {
            // Remove backslash from \' in single quoted values.
            if (m1 !== undefined) a.push(m1.replace(/\\'/g, "'"));
            // Remove backslash from \" in double quoted values.
            else if (m2 !== undefined) a.push(m2.replace(/\\"/g, '"'));
            else if (m3 !== undefined) a.push(m3);
            return ''; // Return empty string.
        });
    // Handle special case of empty last value.
    if (/,\s*$/.test(text)) a.push('');
    return a;
}

console.log(data.map(CSVtoArray));

我从How can I parse a CSV string with JavaScript, which contains comma in data?得到这个函数
我有113个元素，这是唯一一个返回null的元素，我不知道为什么
举个最小的例子：

const re_valid = /^\s*(?:'[^'\\]*(?:\\[\S\s][^'\\]*)*'|"[^"\\]*(?:\\[\S\s][^"\\]*)*"|[^,'"\s\\]*(?:\s+[^,'"\s\\]+)*)\s*(?:,\s*(?:'[^'\\]*(?:\\[\S\s][^'\\]*)*'|"[^"\\]*(?:\\[\S\s][^"\\]*)*"|[^,'"\s\\]*(?:\s+[^,'"\s\\]+)*)\s*)*$/;
const text1 = "3a49c9bb-caaf-48d8-b77c-45161cdf8ff5,Stadtwerke Feldkirch,AT006110,\"Verteilernetzbetreiber,Strom\",http://www.stadtwerke-feldkirch.at ,,,2023-02-13T16:05:03.452Z,2023-02-13T16:05:03.452Z\r";
const text2 = "a601f77b-c7ed-40a8-a639-9baa25ca28a5,Revertera'sches Elektrizitätswerk,AT003540,\"Verteilernetzbetreiber,Strom\",http://www.revertera.at ,,,2023-02-13T16:05:03.492Z,2023-02-13T16:05:03.492Z\r";
const text3 = "a601f77b-c7ed-40a8-a639-9baa25ca28a5,Reverterasches Elektrizitätswerk,AT003540,\"Verteilernetzbetreiber,Strom\",http://www.revertera.at ,,,2023-02-13T16:05:03.492Z,2023-02-13T16:05:03.492Z\r";

console.log(re_valid.test(text1));
console.log(re_valid.test(text2));
console.log(re_valid.test(text3));
