正则表达式怎么写，我修改了还是匹配不准确？

我的表达式是：\"title\":\".*?阴天.*?\",

文本内容是：,"title":"今天-多云","timestamp":1661868634,"out_trade_no":"10000399012022083263"},"title":"今天-阴天","timestamp":1661868634,"out_trade_no":"100003990830"},,"title":"后天-多云","timestamp":1661868634,"out_trade_no":"100003990120221"},,"title":"明天-阴天","timestamp":1661868634,"out_trade_no":"1000039901202208306263010054011"},,"title":"今天-多云","timestamp":1661868634,"out_trade_no":"1000039903010054011"},

我要匹配的是红色圈圈内的（"title":"今天-阴天",）表达式应该怎么修改合适

Answer 1

这个需要匹配出所有title,然后再匹配出"阴天"的title,

我给你一个php语言的例子,你看看吧.

或者一次匹配用下面的正则表达式

Answer 2

很简单，用星号会匹配过多，给个范围就好了

\"title\":\".{2,3}?阴天.*?\"
