Hi

You can use javascript to get it :

function (int i) {
            var test = "1Hello-2Hai-3Bye-4GoodBye";
            var stringarray=test.split("-");
            for (var i = 0; i < stringarray.length; i++) {
                stringarray[i] = stringarray[i].substring(1);
            }
            document.write(stringarray[i]);
        }

You will get the value by index.
