JSON键值的正则表达式 [英] regex for json key value

问题描述

我是regex的新手，我正尝试在以下json中的l_fix之后获取值:

Hi i'm new to regex and i'm trying to grab the value after l_fix in the following json:

{ "id": "626307" ,"t" : ".INX" ,"e" : "INDEXSP" ,"l" : "2,050.59" ,"l_fix" : "2050.59" ,"l_cur" : "2,050.59" ,"s": "0" ,"ltt":"3:08PM EST" ,"lt" : "Nov 17, 3:08PM EST" ,"lt_dts" : "2015-11-17T15:08:33Z" ,"c" : "-2.60" ,"c_fix" : "-2.60" ,"cp" : "-0.13" ,"cp_fix" : "-0.13" ,"ccol" : "chr" ,"pcls_fix" : "2053.19" }

现在我正在使用\d[,](?:\d*\.)?\d+ 但是，这似乎有点蛮力，我相信它可以做得更好.

right now i'm using \d[,](?:\d*\.)?\d+ however this seems a bit brute force and i'm sure it can be done better.

推荐答案

正则表达式似乎不是您所需要的，但是，如果要使用正则表达式，它可能是这样的:"l_fix"\s*:\s*"(.+?)".然后，在第一个组中，您将拥有所要寻找的价值.

A regex doesn't seem to be what you need, however if you want to do it with a regex it could be this one: "l_fix"\s*:\s*"(.+?)". Then, in the first group you'll have the value you are looking for.
