Re: [xsl] Is the first preceding-sibling a processing-instruction?

["Piez, Wendell A. (Fed) wendell.piez@xxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

How about

preceding-sibling::processing-instruction() except
preceding-sibling::node()/preceding-sibling::processing-instruction()

?

Presumably this should get any PI that is immediately behind the context node,
but none that are not. (Untested.)

Cheers, Wendell

I interpreted the initial requirement as "If the first preceding sibling that
is not an empty text() node is a processing instruction, get that".

But the markup as shown as the starting point only has elements, PIs, and text
nodes, so for that content a simple
preceding-sibling::processing-instruction()[1] would give the right answer,
assuming there is always a PI before each element.

Cheers,

E.

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?
