如何匹配带引号的字符串中的转义引号？

Question

/^"((?:[^"]|\\.)*)"/

Against this string:

"quote\_with\\escaped\"characters" more

It only matches until the \", although I've clearly defined \ as an escape character (and it matches \_ and \\ fine...).

Answer 1

It works correctly if you flip the order of your two alternatives:

/^"((?:\\.|[^"])*)"/

The problem is that otherwise the important \ character gets eaten up before it tries matching \". It worked before for \\ and \_ only because both characters in either pair get matched by your [^"].
