[SOLVED] How to make the regex negative lookbehind consume discarded text?

My regex is: /(?<!start )".*?"/ - it searches for quotes in text (actually for string literals in code)

For me, it works perfectly with these cases:

But with cases like this it doesn't:

start "test " start " text" - it will match when I don't want it to (with " start ")

How can I make the regex negative lookbehind consume discarded text?

You can use SKIP FAIL. There are other ways too, if you elaborate:

start\s+"[^"\r\n]*"(*SKIP)(*F)|"[^"\r\n]*"

Or:

\bstart\s+"[^"\r\n]*"(*SKIP)(*F)|"[^"\r\n]*"

\bstart\s+"[^"\r\n]*"(*SKIP)(*F): matches first what you don't want, then it uses SKIP FAIL to remove it from results.
"[^"\r\n]*": All is left is what you want to match.
