Thanks for your reply. I did not know that xsl did not
have the concept of null.

Subject: [xsl] String comparison
Hi,
I am trying to comparing to see is a string is
null,
I have a param named userid, i want to check to
see if
'$userid' is not null.
I tried <xsl:if test="$userid!=''>, this does'nt
seem
to help.
Assuming that line wasn't a direct paste from your
stylesheet (because it's
missing a closing double quote on the test
attribute), then I would need to
see more of your stylesheet (and sample XML) before
commenting further. I
would point out, however, that XSLT/XPath has no
concept of "null"--it is
possible to return an empty string, an empty
node-set, or NaN (not a
number), but null is not defined.
cheers,
b.
