Your second one works for me ... your first one is missing something.

What you have above is an empty expression, not an expression for a 
string of a single space.  That would be:

  select="' '"

or:

  select='" "'

How are you determining QCat is empty?  Are you looking at the file 
in its raw form, or are you perhaps opening the file in an XML editor 
and the editor is for some reason thinking the element is empty and 
presenting it as such?

I hope this helps.
