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]"> <xsl:apply-templates/> </xsl:template> <xsl:template match="news/newsItem[position()=5]"> <a href="more.html">Click here for more</a> </xsl:template> <xsl:template match="news/newsItem[position() > 5]"> </xsl:template> 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. regards -- Edd Dumbill | Director, Useful Information Co. & Pharmalicensing Ltd tel: +44 (0) 702-093-6870 | edd@xxxxxxxxxxxxx | http://usefulinc.com fax: +44 (0) 870-164-0230 | pgp: http://usefulinc.com/edd/pubkey.asc XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
