Javascript -- regex strings

Simple question... I am just baffled how to write the notation.

Example: input='..."aaaa\"bbbb"...'

I need regex to grab the string ignoring nested开发者_开发技巧 quotations.

I guess it can start like: input=input.replace(/[^\\]"...

How can I say 'all characters until a " which is not preceded by a \' ?

Thanks!

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

Inside the quotes can be (a) any character aside from a quote or backslash, or (b) any character if it's escaped with a backslash. Repeat.
