I'm looking for a RegEx to return all the characters between two square brackets, and only the characters, not the brackets themselves.
For example given a string that looks like "[A][B2][1,1][ABC]"
The RegEx should return: A, B2, 1,1, ABC
I have tried various expressions for both String#split and Pattern & Match.
The closest I've gotten was:
String.split("[\\[]*[\\]]"); and Pattern.compile("\\[[^\\]]+(?=])");
Both of these return: [A, [B2, [1,1, [ABC
I've found other expressions that return the values with the enclosing brackets (ie. Pattern.compile("\\[[^\\]]*\\]");) but that is not what I'm after.
Does someone know the correct expression? or is what I'm trying to do not possible?
(?<=\\[).*?(?=\\])
You need lookaheads and lookbehinds.or
(?<=\\[)[^\\]]*(?=\\])
