JavaScript: regex for replacing double curly quotes fails when single ones are present

Question

Input:

"Hello."
"'I'm not.'"

Regex:

/"\b/g // opening quote 
/"\B/g // closing quote

Output:

“Hello.”

”'I'm not.'”

As you can see, the regex works OK when it's just a word. The problem arises when the word is surrounded by single quotes. Not sure what's the problem. Any ideas?

Answer 1

I would try to build the regex on the something-followedBy-notSomething-folowedBy-something approach. So it may look like below:

var input = "\"'I'm not.'\" - said Marry.";
var rex = /"([^"]+)"/g
alert(input.replace(rex, ''$1''))
