Question : Javascript Regex - reformat texetarea entries?

Thanks to HugoHiasl I have a script (below) that APPENDS textarea contents into a
Select List Box (dynamically). How can I use Javscript Regex to reformat the textarea
items as they are appended to the Select List Box?

If the textarea items are formatted like this:

LName1,Fname1,EmailAddress1@something.com;
LName2,Fname2,EmailAddress2@somethingelse.com;

They should be appended to the Select List Box like this:

"LName1, Fname1" <[email protected]om>,
"LName2, Fname2" <EmailAddres2s@somethingelse.com>,

Thanks....!
