This question would have been better suited to ruby-talk, rather than ruby-core.

The unpack string "Z*Z*Z*" will unpack that particular input:

> "apple\0orange\0banana\0".unpack("Z*Z*Z*")
=> ["apple", "orange", "banana"]

This assumes that input always contains just 3 strings. If you have
more they will be ignored.

Not sure if that's what you want, but HTH.
