Regex that matches path string inside url(" ") but not base64

Question

Hi I'm trying a lot about this and I'm not reaching the solution.

I'm reading a CSS file and I want to match the path strings inside the url(" "). In the file there are also base64 sources that starts with url("data: and i don't want those.

EDIT: But now I'm testing with this https://regex101.com/ I digit url\(\".\"\) and it give me nothing.

@Biffen That's not mt case, I know regex but I can't get with this case. — Antonello Gatto, Dec 27 '18 at 12:23
`url\(\".\"\)` (`"` shouldn’t need escaping, BTW) will match a *single* character between the quotes. — Biffen, Dec 27 '18 at 12:32

Use ?! for negative lookahead: url\(\"((?!data:).*)\"\)

https://regex101.com/r/0A8iyF/1 why it gives me just "Group 1. `g`"? He's just grouping the last char? – Antonello Gatto Dec 27 '18 at 12:37

Sorry, typo. Try `url\(\"((?!data:).*)\"\)`. Updated my answer. – Gereon Dec 27 '18 at 12:46
