RE: DOCBOOK-APPS: More performance issues with XSL 1.52.2

[Kraa de Simon <Simon.de.Kraa@services.fujitsu.com>]

Hello,

Please advise.

Currently I have one large book (about 5000 html files) and just don't have
enough time to generate the whole document every night.

Do I understand correctly that splitting the book up into a set of books
won't help me out here because I still have to generate the whole set in one
go?

Because some of the chapters (books) are quite static / don't change often I
would like to skip those.

Do I understand correctly that using olink you can accomplish this?

For example:

book
  chapter 1 - dynamic -> process
  chapter 2 - dynamic -> process
  chapter 3 - static  -> skip
  chapter 4 - dynamic -> process

or

set
  book1 -> process
    chapter 1 - dynamic -> process
    chapter 2 - dynamic -> process
    chapter 3 - static  -> skip
    chapter 4 - dynamic -> process
  book2 -> process
    chapter 1 - dynamic -> process
    chapter 2 - dynamic -> process
  book3 -> skip
    chapter 1
    chapter 2

Thank you,

Simon.

It sounds like you are processing very large documents,
such as sets of books?  You might consider processing
smaller modules and using olinks to connect them.
The 1.52 stylesheets have a new olink implementation 
that makes olinking easier.  I haven't publicized it
yet because 1.52.2 has a little glitch that's fixed
in CVS, but I can help you try it out if you are
interested.
