I suggest using something like these fragments to match your newsItems.
The first case is the normal case, the second case deals with adding
the link in when there's more than 4 elements, and the third case
simply ensures that the surplus elements aren't displayed.
<xsl:template match="news/newsItem[position() < 5]">
<a href="more.html">Click here for more</a>
<xsl:template match="news/newsItem[position() > 5]">
You can make a similar stylesheet for the second page following
this pattern. The mental jump I find one needs to make is away
from trying to count out your elements and concentrate on
matching them instead. I've tested this with XT, by the way.
