Re: Test expression : Is Context Node an ancestor of n

That reminds me, i have a situation where i have

count(ancestor::Menu[1]|$snode)=1

i then changed to 

count(parent::Menu|$snode)=1

and it stop working. Isn't ancestor::Menu[1] and parent::Menu
equivalent since the ancestor axis is going backward?

Likewise, (ancestor::Menu)[1] should give the first ancestor in
document order, that is to say the anciest ancestor of the context
node.

Am i not correct? If so why my xsl stop working (or better, it works
in a way i don't expect) after that change?
