RE: [xsl] using xsl:with-param in apply-templates problem

Hey Jeni ;)

I never knew about built in templates, I guess it makes a lot of sense
really when you think of it!

I've made the addition and now it works fine, thanks very much for your
help. That had me stumped completely, I was writing regex hacks in
python to get round the problem! (it only need to be produced once)

Yes sorry, I did feel a little foolish sending this code fragment just
after David had explained that before! I've made the changes and taken
note, honest ;)

It's certainly a lot more elegant than my xpath, I've made the changes

in this case I'm after the root element's (chapters) ID, I've also been
using parent::*/@ID on another select, which I guess can be changed to
../@ID

Thanks both of you for your help this morning, thanks Jeni for
explaining it so well to a noddy like me!

Cheers
