Well, yes, maybe I should withdraw my comment, although in fact the 
desired functionality is present, as both Mike Rylander and I noted. You 
just need to use the text() function to get the contents of the node, 
and an array subscript to pull it out of the result array.

The really annoying thing we are missing is not xpath functionality, but 
XSLT processing.
