Re: [xsl] Preceding comment() match

[Wendell Piez <wapiez@xxxxxxxxxxxxxxxx>]

Karl,

Please double check your code. I would expect "every preceding 
element's first comment tag" to be 
"preceding-sibling::*/comment()[1]" (note extra step). The expression 
you provided us, "preceding-sibling::comment()[1]", would select the 
first preceding (sibling) comment.

If you want the first preceding node, but only if it's a comment, that would be

preceding-sibling::node()[1][self::comment()]

but note that whitespace-only text nodes can impede that.

Working around those would be

preceding-sibling::node()[not(self::text()[not(normalize-space()])]
                         [1][self::comment()]"

... which I know is a monster, but there you have it.

Cheers,
Wendell
