"empty node" is not a defined term. It is a node representing an empty
element.
> 2. what's wrong with my not() function ?
Nothing, but it is never true.
<xsl:when test="not(.)"/>
. is the current node, so not(.) is true if the node set containing the
current node is empty, but it is never empty.
You want
<xsl:when test="not(node())"/>
which is short for
<xsl:when test="not(child::node())"/>
and tests if the current node has child nodes (including text and
comments etc.
