The question said "white space". Not "white space character".
Also in your message you were describing the solution to your "first case" as:
"For the first definition, one might want
translate(product/text(),'
	',' ')=' ' "
So, it seems that your "first case" defines whitespace as containing one or more newline and tab characters. There is nothing in your proposed XPath expression that restricts the test for "*only* a single character".
Cheers, Wendell
