如何在Regex中的引号中获得带有引号内部值的所有值？

发布于 2025-01-18 11:24:31 字数 429 浏览 2 评论 0原文

我试图使用正则表达式获取引号中的每个值，在某些情况下我得到它，而在其他情况下我没有。

我的正则表达式：/(?:-reason|-r) ?"(.+?)(?:"-|" -|"?$\B)/g

下面是我测试过的一些句子，第 1 行和第 2 行与正则表达式匹配，但第 3 行不匹配。

1 anything -reason "some reason" -anyArg "anything"
2 anything -reason "Hello World, you're the "best"" -anyArg "anything"
3 anything -r "anything "here" is wrong" anything

图像的最后一句与正则表达式不兼容，我该怎么做才能使正则表达式全部匹配？

原文

I'm trying to get every value in quotes using regex, in some situations I get it and others I don't.

My Regex: /(?:-reason|-r) ?"(.+?)(?:"-|" -|"?$\B)/g

Below are some sentences I've been testing, line 1 and 2 match regex, but line 3 doesn't.

1 anything -reason "some reason" -anyArg "anything"
2 anything -reason "Hello World, you're the "best"" -anyArg "anything"
3 anything -r "anything "here" is wrong" anything

The last sentence of the image is not compatible with the regex, what do I do to make the regex match them all?

使用

-r(?:eason)?\s*"(.+?)(?:"\s*-|[^"]*$)

请参见 Regex Prace 。

Use

-r(?:eason)?\s*"(.+?)(?:"\s*-|[^"]*$)

See regex proof.
