In Java what should be the regex, if i need the text withing the quotes as one element? -

-

my input string is:

apple, orange, "banana,cherry", peach

i need output as:

apple orange banana,cherry peach

i have tried using regex as:

",(?=([^\"]*\"[^\"]*\")*[^\"]*$)", -1

...in split() method of java, output as:

apple, orange, "banana, cherry" peach

this 1 should work, though regex should figure out yourself. gods if ever want change in it; since didn't design monster you'll have no clue how works.

and monster is, believe me.

\s*("?)\s*([^",]+?(\s*,\s*[^",]+?)*?)?\s*\1\s*(,|$)

basically, puts in optional quote @ start , makes capture group out of it, ("?), , uses backreference \1 later in regex make sure matched content should either surrounded quotes, or not have them @ all.

the rest whitespace , comma-separated content of format "optional stuff" + "repeating optional stuff starting comma", using "not quote or comma" group [^",] indicate actual text content match.

capture group #2 contain data between commas need, trimmed @ both sides, , taking stuff between quotes 1 match.

note out of necessity capture text behind final comma, forced make matched content end on "comma or end of line", means multi-line content between quotes (which exists in excel csv output) not matched correctly.
