Regexp matching of list of quotes strings - unquoted

in Javascript, the following:

var test = '"the quick" "brown fox" "jumps over" "the lazy dog"';
var result = test.match(/".*?"/g);
alert(result);

yields "the quick","brown fox","jumps over","the lazy dog"

I want each matched element to be unquoted: the quick,brown fox,jumps over,the lazy dog

what regexp will do this?

For matching content between pairs of simple quotes and double quotes taking care of escaped ones.

As search engine first drove me here, I really would like to orient people looking to check quotes pairs to the more generic question: https://stackoverflow.com/a/41867753/2012407.

The regex will get the full content between well formed pairs of quotes like '"What\'s up?"' for instance that are not in a code comment like // Comment. or /* Comment. */.

grapefrukt's answer works also. I would up using a variation of David's

match(/[^"]+(?=("\s*")|"$)/g)

as it properly deals with arbitrary amounts of white space and tabs tween the strings, which is what I needed.

This is what I would use in actionscript3:

var test:String = '"the quick" "brown fox" "jumps over" "the lazy dog"';
var result:Array = test.match(/(?<=^"| ").*?(?=" |"$)/g);
for each(var str:String in result){
    trace(str);
}

It is not one regexp, but two simpler regexps.

var test = '"the quick" "brown fox" "jumps over" "the lazy dog"';

var result = test.match(/".*?"/g);
// ["the quick","brown fox","jumps over","the lazy dog"]

result.map(function(el) { return el.replace(/^"|"$/g, ""); });
// [the quick,brown fox,jumps over,the lazy dog]

This seems to work:

var test = '"the quick" "brown fox" "jumps over" "the lazy dog"';
var result = test.match(/[^"]+(?=(" ")|"$)/g);
alert(result);

Note: This doesn't match empty elements (i.e. ""). Also, it won't work in browsers that don't support JavaScript 1.5 (lookaheads are a 1.5 feature).

You can use the Javascript replace() method to strip them out.

var test = '"the quick" "brown fox" "jumps over" "the lazy dog"';

var result = test.replace(/"/, '');

Is there more to it than just getting rid of the double-quotes?

Here's one way:

var test = '"the quick" "brown fox" "jumps over" "the lazy dog"';
var result = test.replace(/"(.*?)"/g, "$1");
alert(result);
