RE: counting the element number in a recursive tree

If position() returns even numbers, it's because you are counting text nodes
as well as elements. The answer is to count only the elements, which will
happen if you use <xsl:for-each select="*"> or <xsl:apply-templates
select="*"> rather than using select="node()".

Dividing position() by 2 is wrong, because the whitespace text nodes won't
always be there.

Alternatively, use xsl:number.
