Whitespace is a tricky thing to get right. It's impossible to give you a
good answer without knowing more about what you are trying to do and
why, and the context, and without seeing your XSLT.

In some contexts, . eq ' ' would work, for example, and in others you
might want data(.) eq ' ' (both assuming XSLT 2) or even something like,
    matches(., '^\s+$')
