Re: Counting preceding nodes

Billie,

At 01:29 PM 6/24/2005, you wrote:
I gave the diagrams the appropriate names so you could see what I was looking for, but basically, I'm looking for a way to number the diagrams based on the absolute order in which they are placed.

This statement of the problem suggests it might be handled with the xsl:number instruction, which is designed to do this.

You might want <xsl:number level="any"/>. A good XSLT reference will help.

I've tried all sorts of combinations but nothing seemed to work. One logical structure I came up with, that I couldn't figure out how to translate into XSL, was: "count the number of diagrams that have an ancestor-or-self which is a preceding-sibling to an ancestor-or-self of the diagram in
question".  Is that possible to do?

Yes (sort of), but there are also easier ways, such as using "count(preceding::diagram)". You don't need to worry about counting ancestors unless diagrams are allowed to contain other diagrams.

But xsl:number is the thing to use unless there's some reason not to.

Cheers,
Wendell
