How can I list an array but exclude the empty cells?

I would like to list the contents of an array on the x dimension but exclude the cells that are empty (0).

So if I have an array of words like this [Play] [0] [0] [Fire] when I display them this is what happens:

Play

0

0

Fire

What I need is:

Play

Fire

Thank you.

If you're using loop, insert [condition: int(array.at(loopindex)) ≠ 0].

Thank you.
