Everything is possible, but your description is incomplete.. A string is not numeric, so do you want to remove the elements taht have the character zero or do you want to remove elements that have empty strings, or both?

What have you tried so far? There ae plenty of examples posted in the forum to do this. Is this homework?

Try this, credits for DFGray: http://forums.ni.com/t5/LabVIEW/Dr-Damien-s-Development-Memory-Allocation-in-Loops/td-p/1075712

You probably could put Trim Whitespaces for empty strings with 1 or more whitespaces before.

If you have a recent LabVIEW version, all you need is a conditional output tunnel as follows:

What is the purpose of the outer case structure?

Here's a much simpler version of the same (LV 2010).

If you feel like my version is still a little complicated, please vote for my idea here. 😄

This is NOT my vi! Yes, that version is LabVIEW 2012 and was posted by someone else. It is also overly complicated (see my picture above).

Have you tried downloading my suggestion. It is guaranteed to be in LabVIEW 2010 and contains significantly simpler code while giving the same result. 😄 That's all you need!
