Text parsing/list cleaning question

Hi,

I am importing a text file with numbers, each line becomes a list item.

The problem is that the last line may be a "blank" (just a carriage return), this leaves a blank line at the end of the list.

So, I'm not sure how to modify the parser to ignore these lines...

Otherwise, how do I clean a list that might have blank lines...  They're not considered as nothing somehow, I don't know how to cull them...  Even if I graft each line into a separate branch, the "empty" line branches are neither considered null nor empty...

TIA, --Mitch

Edit: OK, I found there was actually also a space after the CR at the end...  If there is just a CR, it's OK...  And if there is a CR in the middle, I get an <empty> on that line.  Other than grafting, cleaning and re-flattening, is there a way to remove those lines at list level?
