如何在kotlin中查找单词的所有表达式

Question

fun main(args: Array<String>) {
val text = " "id": "5jaq2", "mood"  "id": "RKlvj", "is_verified"  "id": "XPyZj", "mood""
val regex = Regex("id": (.*?)[,]")
val matches = regex.findAll(text)
val names = matches.map { it.groupValues[1] }.toList()
println(names)
}

我想找到所有的id，但是如果"；is_ verified"；是在id之后，我不想把它放在列表中。

当前结果：["5jaq2"，"RKlvj"，"XPyZj"]

预期：["5jaq2"、"XPyZj"]

知道如何正确地做到这一点吗？

尝试使用：

val regex = Regex("(?:"id":\s)(["\w\d]*?)(?:,\s)(?!"is_verified")")

说明：

(?:"id":\s)      // Non-capturing group to match {"id": }
(["\w\d]*?)      // Capturing group to catch only words, digits and quotation marks characters
(?:,\s)            // Non-capturing group to match {, }
(?!"is_verified") // Negative lookahead to not match if the next letters are {"is_verified"}
