True!

I guess what the original author really meant was to check if the 
element is "empty or non-white" - because the data stored in anElement 
would be a car's license number and it makes no sense to return spaces 
(which are invisible on the print-out) when there's alternative data 
stored (which he retrieves in the otherwise-branch).

I reckon my test with normalize-space() is more accurate.

Thanks,
