使用正则表达式获取子字符串（带有“”的字符串）

Question

I have a main string like this:

const mainString: string = `
let myStr: string = "Hello world";
function x() { }
let otherVar: number = 4;
let otherString: string = "Other string value";
// something else INSIDE the main string
`;

Now I need to format this main string, but substrings cause unwanted stuff, so I need to get them.

The regex I used until now was: /"([^"]*)"/g . With it I would get eg ['"Hello world"', '"Other string value"'] (in the mainString context from above).

But having a "\\"" inside one of these substring, would throw off my regex and give me the part from the beginning until the \\" and then, if some other substring was used anywhere else, give me the real end of the substring " (falsly as a start symbol) until the start of the next substring...

One important thing: I have absolutly no control what so ever about anything before and beyont the "substring value" .

What would be the correct regex for my usecase?

Answer 1

Try this one

"((\\"|[^"])*?)"

\\\\" - mean look for \\"

| - or

*? - for no greedy
