When a lot of people come to XSLT they see <xsl:for-each> and think "That's
what I need" when it most times isn't. They should be using templates. As
they start to develop their template they add <xsl:if> and <xsl:choose> all
over the place within the <xsl:for-each> to get round not using templates in
the first place. So to stop people making a bealine for <xsl:for-each> I
always say "Beginners rule #1 *NEVER* use for-each". Daniel's solution to
his own problem is

Next he will be asking how he can increment his $Index variable which he
can't do because you can't increment variables without using recursion. As
he hasn't got the hang of templates yet explaining to him how to do
recursion is not going to be easy.
