Not entirely true..
You can always use the position() function, but it depends on the
context list, what it actually returns. The context list corresponds
more or less to the last issued for-each's select statement or
apply-templates's select statement. Both select's return a node set,
which is ordered according to supplied sort instructions or in document
order by default. That is used as context list.
What you need to do here to be able to use it, is to integrate your
*outer* if statement with the for-each select statement. As mentioned
before, you can add a predicate to your xpath. Inside the loop, you can
do stuff like:
<xsl:for-each select="a/b/[EMAIL PROTECTED] = '']">
<xsl:if test="position() = 1">
..
</xsl:if>
<xsl:if test="position() = last()">
..
</xsl:if>
<xsl:if test="not(position() = last())">
..
</xsl:if>
</xsl:for-each>
You can also use the position() outside a for-each, but might appear to
be confusing for others. By just looking at one template, you cannot say
for sure whether comments and text nodes (like white-space) are counted
as well or not.
