I would use

preceding-sibling::processing-instruction()[1]

And I think it means "of my preceding siblings nodes which have node
type processing instruction, I want the one closest to me".

Have I got that wrong?  Or is it only wanted if there's no intervening
node that's not a white space only text node?
