removing elements from multidimension array

[HarryKlein]

Hi All,

I create a multidimensioned array by splitting a file by crlf-s then splitting each elements in the resulted array by field separator, like this:

I would like to get rid off some elements in the first array based on some criteria, e.g they are empty or they contains spaces only.
Is there any way to do on some efficient way?

Thanks

I would like to eliminate the - s.
