I've the string looking like this:

word1-word2-word3-\d{1,2}\w?-\d{1,2}\w?|word1-word2-\d{1,2}\w?-\d{1,2}\w?|word1-word2-word3-(\d{1,2}\w?\d{1,2}|\d{1,2}\w?)-\d{1,2}\w

I'd like to split this string by '|' everywhere where it doesn't precedes by '('. So result should be: 

["word1-word2-word3-\d{1,2}\w?-\d{1,2}\w?", "word1-word2-\d{1,2}\w?-\d{1,2}\w?", "word1-word2-word3-(\d{1,2}\w?\d{1,2}|\d{1,2}\w?)-\d{1,2}\w"]

I've trying to use negative lookahead \((?!\|) which split the text to on '('.

UPDATE

So I want to achieve not splitting the "word1-word2-word3-(\d{1,2}\w?\d{1,2}|\d{1,2}\w?)-\d{1,2}\w" on '|' where that character is precedes by '('.

Could someone please help me with this?

Code:

public static void main(String[] args) {
        String str = "word1-word2-word3-\\d{1,2}\\w?-\\d{1,2}\\w?|word1-word2-\\d{1,2}\\w?-\\d{1,2}\\w?|word1-word2-word3-(\\d{1,2}\\w?\\d{1,2}|\\d{1,2}\\w?)-\\d{1,2}\\w";
        String[] arrOfStr = str.split("\\|");

        for (String a : arrOfStr)
            System.out.println(a);
    }

  • This would also split on `|` which is inside parenthesis which OP doesn't want. – Pshemo Oct 02 '19 at 12:03
  • Oh, sorry I just saw the update – Kane01 Oct 02 '19 at 12:04
