Re: an Xpath question - $tag/$subtag

2003-07-08 01:57:31

It's not a very useful
expression, because the result doesn't depend on the value of $v1,

 $v1/$v2 does depend on $v1 being empty (or not) doesn't it?
Isn't it
if empty($v1) then $v2 else ()

(Just in case you were planning to optimise it away:-)


But this user was after dyn:evaluate(concat( $v1, "/", $v2 )) which is
something quite different, and is NOT available in XPath 2.0.

Yes, but you only knew that because you are really Jeni and can divine
users' real questions from no information.
