how to find elements that don't have ancestor

[kishjeff]

Hi.

Can someone tell me how to find all the elements of type 'table' which
have an attribute named 'source' and are not descendents of
'querybox' ?

I'm sort of wrestling with it and am hoping someone can tell me if it
is possible.

I know it is possible to find all elements that ARE descendents of
'querybox' that have a given attribute and are of a certain type.

Why not :
//table[@source and (count(ancestor::querybox) = 0)]

Cheers,

thanks so much. that works just fine evidently. is there a way of
doing it without count, say with some sort of "not
decendent::querybox" sort of thing?

regards in any case

You did most of the work ;-)

< is there a way of

Just try not(descendant::querybox)

not() is a *function*, hence the parentheses.

XPath 2.0 also introduces some other functions like exists().

Be aware that not(descendant::querybox) it is not what you have asked

Cheers,
