new to the list/ DocBook publishing portially

Hello everybody,

I惴 new to the list, but I惴 very happy that I found it, because I惴 
sure somebody can help me in here.

 I have a pretty big DocBook (with many include directives) and like to 
make it online available. But with the Feature, that you can choose 
which Chapters will be in the pdf/html.
Does anyone know if there is some project/app/implementation or 
something, that already offers this feature?

thank you for any help

greetings
Pete
