[xquery-talk] Except in XQuery

[padmapriya ayyagari]

Hello,

I'm trying the following implementation for some kind of deep-except,
wherein a branch of an xml document is removed.

define function myExcept($n,$omit){

        for $c in ($n/child::node() except $omit)
        return
                element{name($c)} {$c/@*, $c/text(), fn:myExcept($c,$omit)}
}

If i say myExcept(fn:doc("xmark.xml")/*,fn:doc("xmark.xml")/site/people/person/watches/watch),
it returns the correct result, along with
<site><people><peson><watches><watch></site></people> ...
basically an empty element corresponding to the branch that has been
removed. Why do you think this is happenign?

By the way, I'm using Galax 0.3.1. 

Thanks,
padmapriya
