AS2:: Breaking up a string

I have a string that looks something like this:

00110; book1,book2,book3,: 6

What I need to do it spilt it up into sperate values by the semi colon. so in the end it would be like

String1 = 00110
String2 = book1,book2,book3
String3 = 6

Can anyone give me any ideas on how to go about it?
