Problem.

The 'number' I'm getting back is different in each case.
In the former case I get 1 to 7,

Because you are only selecting 'section' elements.

in the latter case I get 2 6 10 14 18 22 26

Can anyone suggest why they are different please?

Because you are probably selecting more than section elements.

Perhaps you are in <body> and you are asking that all child nodes be pushed through your stylesheet with <xsl:apply-templates/> (with no select= attribute) ... you are going to get *all* child nodes of <body> pushed, not just <section> nodes.

  <body>
   <title/>
   <section/>
   <section/>
   <note/>
   <section/>
  </body>

The sections above would be counted as 4, 6, and 10 due to the intervening element nodes and the intervening text nodes. It is often the text nodes that I forget about. I've illustrated this with a diagram on page 58 of the 7th edition.

The SHOWTREE stylesheet in the free resources section of our web site exposes a report of all nodes in the instance ... run your input through that stylesheet to see all of the intervening nodes.

I hope this helps.

............... Ken
