Split text by line enter

Hi - My text has a bunch of one liners that are split by a line break. How can I split by a linebreak to turn the long text into a repeating group for each line and filter out empty lines?
For instance, the text looks like :
"A

B

C

D"

and I would like it to look like (ie is a repeating group):

__ A__
__ B__
__ C__
__ D__

Use ‘split by’ line break (i.e. press the enter key).
