Your split should work. Take care with your Array though. Array#<<  
appends the object you give it to an Array. String#split returns an  
Array so what you end up with is an Array which *contains* the Array  
generated by split. Perhaps Array#+ is what you need?

irb(main):009:0> array = []
=> []
irb(main):010:0> string = "hi\tthere"
=> "hi\tthere"
irb(main):011:0> string.split("\t")
=> ["hi", "there"]
irb(main):012:0> array << string.split("\t")
=> [["hi", "there"]]
irb(main):013:0> array += string.split("\t")
=> [["hi", "there"], "hi", "there"]

Also look up Array#join to make your life easier.
