Question

我有一个String，如下所示。它是 NOT JSON

"city":"atlanta","this1":"that1","state":"GA","city":"dallas","this2":"that2","state":"TX"

我的要求是使用正则表达式获取给定州的城市名称。在城市和州参数之间我可能有不同数量的参数。

这个正则表达式模式似乎是贪婪的 - 匹配上面的字符串

的亚特兰大城市

"city":"(.*?)".*?"state":"TX"

匹配

"city":"atlanta","this1":"that1","state":"GA","city":"dallas","this2":"that2","state":"TX"

我正在寻找这样的比赛。

"city":"dallas","this2":"that2","state":"TX"

如何仅在TX中匹配？

为什么你不尝试这样的东西，这看起来比正则表达式容易得多。

public class TestStack {

    public static void main(String[] args) {

        String s="\"city\":\"atlanta\",\"this1\":\"that1\",\"state\":\"GA\",\"city\":\"dallas\",\"this2\":\"that2\",\"state\":\"TX\"";

        String[] arr=s.split(",");

        for(int i=0;i<arr.length;i++){

            if(arr[i].contains("city")||arr[i].contains("state")){
                System.out.println(arr[i]);
            }

        }

    }

}

正则表达式 - 使比赛不贪婪
