Re: Automatically generate xpath

you dont want to remove nodes from a xpath (which is an expression) but
from a node set (which is a value). So you are asking for set
difference: given two node sets $a and $b generate a set of nodes in $a
but not $b.

As I think someone showed earlier, in XPath2 this is

$a except $b

in XPath1 set difference isn't a standard operator but it's available
using the standard idiom:

$a[count(.|$b)!=count($b)]
