SPUG: question regarding using reg exp in "if" statements.

I have written an "if" statement:
if ($string eq "") { whatever;}
else{ something else;}
to check for blank entries in a form CGI. This works except that " "
doesn't satisfy the if statemenet condition.
What I really want is (in plain English) is:
if ($string is only white space)
I've tried stuff like:
if($string eq /\s/)
if($string ne /\w/)
if($string eq m/\s/)
if($string ne m/\w/)
etc.
but they don't work. I'm probably missing something obvious, but I can't
figure it out. Any help would be appreciated. Thanks.
