How to get all values between quotation mark with quotation marks inside value in regex?

Question

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?

Please don't use pictures of code and data. For one, readers cannot cut-and-paste in constructing answers. — Cary Swoveland, Apr 03 '22 at 03:58
@Nick I believe the "solution" you reference requires that internal quotes be escaped, e.g. `"abc\"def\"ghi"`. See [this](https://regex101.com/r/OgoUlQ/1) and [this](https://regex101.com/r/WmuOCs/1). — Booboo, Apr 03 '22 at 11:44
@Booboo that's correct - but I don't see that there are any internal quotes in OPs data, although it's hard to be 100% certain since they have not indicated their expected result from line 3. — Nick, Apr 03 '22 at 12:17
@Nick Look at Sentence 3 above: **anything -r "anything "here" is wrong" anything** (presumably the match wanted is **"anything "here" is wrong"**). But then why is Sentence 2. not a problem, also? — Booboo, Apr 03 '22 at 14:00
You need to specify for each sentence what exactly the expected match should be. — Booboo, Apr 03 '22 at 14:09

Use

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

See regex proof.
