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.
