Hm (Mick),

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).

And now I'm thinking that to work around the type-conversion rules you may have to do

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

since otherwise your node-set will be turned into a string before it's made a Boolean and then a number.... :->
