Re: [xsl] Suggestions for naming files based on starting node?

[Chris von See <chris@xxxxxxxxxxxxx>]

I tried inserting <xsl:number> into the template where the file names  
are generated, but I couldn't get it to give me anything but the same  
number over and over again - I'm not totally sure why.  I tried  
several combinations of level and count settings, but got the same  
result each time.  Sometimes the output was zero, sometimes another  
number, but it was always the same number over and over.

There are a few factors that might have come into play to cause this:

-- The template that generates the file names is separate from the  
one that actually creates the files using <xsl:result-document> so  
that it can be called from any location where it's necessary to  
determine what XHTML file a given node will be in.  This includes not  
only the bit that actually contains <xsl:result-document>, but the  
TOC generator, the hyperlink resolver, the note/annotation/index/ 
glossary cross-reference resolvers, etc.  This file name generator  
template (I'll probably convert it to a function at some point) has a  
"mode" attribute to restrict processing.

-- The template that generates file names matches on "*", not just on  
the elements that need numbering, because of the need to determine  
what file an arbitrary node is (or will be) in.  There is a bit of  
logic in this template (the actual file name generation part) which  
is executed only for the nodes that need numbering, and that's where  
I put the <xsl:number>, but since the numbering was wonky I wondered  
if the generic template match confused the XSLT processor.  I could  
separate this logic into two templates - one for the nodes that need  
numbering and one for the nodes that don't - and I'll probably try  
this at some point just to see if it makes a difference.

-- The template that generates file names is heavily recursive, and  
uses internal logic to determine when to recurse.  I wouldn't think  
this would really be a factor, but it might be.

I freely admit that my lack of experience writing really complicated  
XSLT may be my worst enemy here.  If you have suggestions on how to  
handle situations like this (breaking long XML documents into  
multiple XHTML with cross-linking - not exactly an uncommon  
scenario!) or can point me to reference material that gives examples  
of techniques for doing this, I'd appreciate it.


Thanks
