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(),'&#xA;&#x9;',' ')=' ' "

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
