Here's an example (last name substring is in its own JS
function ( getLastName()) )....I'm using the same convention
of the "String" format as you originally provided and the list
contains, I believe, 8 names.
The list is a multiple selection listing. Pick some or all and
then "hit the button" to see the results. Have fun...

<script type="text/javascript">
function sortResults(form) {
var count = 0;
var listObj = form.urlList;
var sortArray = new Array;
var temp;
for (var i=0;i<listObj.length;i++) {
if (listObj.options[i].selected) {
sortArray[count] = listObj.options[i].value;
count++;
}
}
if (sortArray.length > 0) {
var unsorted = false;
var thisVal;
var nextVal;
do {
unsorted = false;
for(var i=0; i<sortArray.length-1; i++) {
thisVal = getLastName(sortArray[i].toLowerCase());
nextVal = getLastName(sortArray[i+1].toLowerCase());
if (thisVal > nextVal) {
temp = sortArray[i];
sortArray[i] = sortArray[i+1];
sortArray[i+1] = temp;
unsorted = true;

function getLastName(stringIn) {
var startPos = stringIn.indexOf(".");
var endPos = stringIn.indexOf("@world");
return(stringIn.substring(startPos+1,endPos));
