xsl if null
Hi All, first thank you very much from your answers, im very much
enlightened about what my problem was.

my xml reply is just returning either <sample /> if empty or
<sample>abc</sample> if not and <sample> node don't have any children
at all.
so DC's node() won't work either.

and none of the suggestions can solve it either.

more power to the group!
