So by "next" do you need the "closest" <endofpage> element to the 
start of each given section with a <toc>?

Since you are already in a section's child, that would entail going 
up to the parent of <toc> and down as well as those that follow, so 
the first of the union of those addressed elements:

  (..//endofpage | ../following::endofpage)[1]

... though I would strongly suggest you revisit your XML to see if 
the <endofpage> can be more logically positioned.  I understand of 
course that many times we have to deal with what we are given, but it 
would seem to me there are too many opportunities for a misplaced 
<endofpage> element.

I hope the example below helps.
