It depends on the processor. But I am not sure what you mean by
exactly behind or exactly in front of.
You don't set XPointers - you use XPointers to refer to a fragment of
a document in the URI you pass to the document() function.

No, you can access elements via any XPath expression.

It depends upon which XSLT 2.0 processor you are using. As far as I
know, there are none that support the XPointer scheme (which is not a
W3C recommendation - only the element and xmlns schemes made the
recommendation).
Gestalt has a gexslt:xpath2 scheme, so you could use that to select
the nodes you want.
I think the XPath expression you want is (assuming the first div you
show is the first child element of the document element):
/*/div[1]/*[position gt 2 and position lt 7]

It does matter. Which XPointer schemes (if any) are supported by an
XSLT processor is implementation-defined.
