This code will extract all the characters as a group, but the commas are still there. You could use the String.split() method the extract the comma delimited Strings. The regex I came up with presupposes that there will always be at least one comma in the values, no commas outside of the values, but as many values as you want. If these assumptions don't match the actual problem, you'll have to adjust the regex accordingly. i.e. it will match: a,b,c a,b,c,d,e,f a, abc,def,ghi
but not: a abc

Thanks for your reply.
Finally, I'd updated the pattern to the following to extract the (). And then I put the result into the matcher agin to get the result.
