(this is the same bug as reported by Sergio Carvalho)

it's because esql:get-xml resulted in an xsp expression, which must be
evaluated in the context of an element in the result tree. i just
committed a patch which tries to work around this by checking to see if
esql:get-xml's parent is esql:row-results and generating different source
if so. check it out of cvs, please, and give it a whirl. thanks.
