RegEx使用RegExp.exec从字符串中提取所有匹配项 [英] RegEx to extract all matches from string using RegExp.exec

问题描述

我正在尝试解析以下类型的字符串:

I'm trying to parse the following kind of string:

[key:"val" key2:"val2"]

其中有任意键:"val"对.我想获取键名和值. 对于那些好奇的人，我试图解析任务战士的数据库格式.

where there are arbitrary key:"val" pairs inside. I want to grab the key name and the value. For those curious I'm trying to parse the database format of task warrior.

这是我的测试字符串:

[description:"aoeu" uuid:"123sth"]

旨在强调除空格外，任何内容都可以位于键或值中，冒号周围没有空格，并且值始终用双引号引起来.

which is meant to highlight that anything can be in a key or value aside from space, no spaces around the colons, and values are always in double quotes.

在节点中，这是我的输出:

In node, this is my output:

[deuteronomy][gatlin][~]$ node
> var re = /^\[(?:(.+?):"(.+?)"\s*)+\]$/g
> re.exec('[description:"aoeu" uuid:"123sth"]');
[ '[description:"aoeu" uuid:"123sth"]',
  'uuid',
  '123sth',
  index: 0,
  input: '[description:"aoeu" uuid:"123sth"]' ]

但是description:"aoeu"也与此模式匹配.如何找回所有比赛?

But description:"aoeu" also matches this pattern. How can I get all matches back?

推荐答案

继续循环调用re.exec(s)以获得所有匹配项:

Continue calling re.exec(s) in a loop to obtain all the matches:

var re = /\s*([^[:]+):\"([^"]+)"/g;
var s = '[description:"aoeu" uuid:"123sth"]';
var m;

do {
    m = re.exec(s);
    if (m) {
        console.log(m[1], m[2]);
    }
} while (m);
