Re: [docbook] XSL - Getting the Chapter number

Hi John,

First, if you are using the -ns- namespaced 
stylesheets with DocBook 5 documents, make sure that all instances of element 
names in your customization layer have the docbook namespace prefix, otherwise 
they won't match on your elements.  So if it currently has "chapter", it 
should be changed to "d:chapter" with the namespace declaration at the 
top.

 

Without further review, it is hard to say why 
position() no longer works.  That can be a tricky function to use, as 
described in this recent email exchange:

 

http://lists.oasis-open.org/archives/docbook-apps/201105/msg00007.html

 

The DocBook stylesheets include a number of utility 
templates, including those for numbering elements. They  use 
mode="label.markup", and simply return the number of the element. You can use 
something like this in a template matching on d:chapter:

 

<xsl:apply-templates select="." 
mode="label.markup"/>

 

See this reference for more on the utility 
templates:

Subject: [docbook] XSL - Getting the 
  Chapter number

  

  
I am currently moving a 4.2 docbook file at work to use docbook 5.0 and I 
  am nearly finished, though I have stumbled on a problem.

  

  
The problem I have is with a custom style sheet that is used at work, it 
  made used to an old version of the docbook-xsl files that are found at the 
  sourceforge, and when I updated the 4.2 xml file I downloaded the latest 
  version of the docbook-xsl-ns files and started to change the custom xsl sheet 
  to work.

  

  
The custom style sheet in question is used to translate the xml file into 
  the fo format so that it can be converted to a pdf document.  At one 
  point in the custom xsl sheet the original author stuck in a call to the 
  position() function in a chapter template to get the current chapter number 
  for a page header.

  

  
Though the use of position() does not appear to work after the update 
  with the chapter numbers for that page header start with 2 instead of 
  1. 

  

  
This actually doesn't affect the other instances of the where the chapter 
  number is used, like in the pdf's bookmarks or the table of contents, which 
  leads me to believe that there must be some method in the docbook-xsl-ns fo 
  files that can be used to to get the current chapter number, as opposed to 
  ending up using "position()-1"

  

  

  
Any ideas?
