Re: Key to select all same nodes(same @id) except curr

best to say of you want xslt1 or 2.

in 2 

key('ParentKey',@id) except .

will return all category elements with the current id except the current
node.

in 1 you'd write it as

key('ParentKey',@id)[not(generate-id()=generate-id(current()))]

> <category> element.

not sure what you mean by top element. If you mean ancestor then in 2
that's


key('ParentKey',@id) intersect ancestor::category
