I would like to match the comma's which are only outside the double quotes

I have written a regex as (?!(\"){1}(^\")*(\"){1})(,)

But this is not working!!! Can anyone please let me know the problem with this regex and correct it

The example is as follows : If the string is abc,def,"ghi,jkl,mno",pqr,stu,"wxy" If we do split on , by using regex then output should be should be as follows

abc
def
ghi,jkl,mno
pqr
stu
wxy

Oh, this is not that difficult as you wrote. Just match all double quoted substrings and capture them, use an alternation operator `|` and add a `,` as a separate branch. Or vice versa. You may then replace the comma with some character you won't be using and split with it. – Wiktor Stribiżew Apr 07 '16 at 14:09
Looks like he's doing a CSV field parsing. – Chris Cudmore Apr 07 '16 at 14:09

If it is CSV, use a CSV parser. – Wiktor Stribiżew Apr 07 '16 at 14:10
I need to do this using split method of java – Guy Sackman Apr 07 '16 at 14:11
