Split attribute with multiple values into Array

I have a text attribute which contains multiple values separated by a carriage return. What I want to do is split out each each value into it's own part of an array. I'm assuming I'd need to use "\n" to do the split, but not sure how to go about doing so. Any ideas on how I can accomplish this? Thanks in advance for any help you can provide.
