Java split string with regex, anything inside Double Quotes [duplicate]

Regex for splitting a string using space when not surrounded by single or double quotes (15 answers)

Closed 10 months ago.

I am trying to split a string such as String s = "do not split this \"split this\"";

String[] split = s.split("(?<=\\s)| (?=\") | ((?=[^A-Za-z0-9])|(?<=[^A-Za-z0-9]));

will give me ["do", " ", "not", " ", "split", "this", " ", "split this"];

I would like to keep all words, white spaces as well, but ignore anything inside double quotes~

回答1:

just a guess:

String s = "do not split this \"split this\"";
String[] split = s.split( "(?<!\".{0,255}) | (?!.*\".*)" );  // do, not, split, this, "split this"

don't split at the blank, if the blank is surrounded by quotes
split at the blank when the 255 characters to the left and all characters to the right of the blank are no quotes
