Re: [xsl] Immediately preceding-sibling

[Wendell Piez <wapiez@xxxxxxxxxxxxxxxx>]

Mick,

The simplest XPath test to check whether the immediately preceding sibling 
is a 'nospace' is:

preceding-sibling::*[1][self::nospace]

which retrieves the nospace node (which evaluates to Boolean "true") if the 
immediately preceding node is a nospace; if not, it retrieves nothing 
(which evaluates to Boolean "false").

If you want to be *really* fancy:

substring(" _",1 + preceding-sibling::*[1][self::nospace], 1)

will give you a " " or a "_" depending on what the immediate preceding 
sibling is (since a Boolean false or true becomes the number 0 or 1 when 
you try to add it).

Cheers,
Wendell
