Splitting on comma outside quotes [duplicate]

Answer 1

You can do this very easily without complex regular expression:

1. Split on the character ". You get a list of Strings
2. Process each string in the list: Split every string that is on an even position in the List (starting indexing with zero) on "," (you get a list inside a list), leave every odd positioned string alone (directly putting it in a list inside the list).
3. Join the list of lists, so you get only a list.

If you want to handle quoting of '"', you have to adapt the algorithm a little bit (joining some parts, you have incorrectly split of, or changing splitting to simple regexp), but the basic structure stays.

So basically it is something like this:

public class SplitTest {
    public static void main(String[] args) {
        final String splitMe="123,test,444,\"don't split, this\",more test,1";
        final String[] splitByQuote=splitMe.split("\"");
        final String[][] splitByComma=new String[splitByQuote.length][];
        for(int i=0;i

This will be much cleaner with lambdas, promised!
