Hi Vasu,
would the following statement
<xsl:template match="node">
....
<xsl:when test="count(*)=0"> ( to check for empty child elements)
----
</xsl:template>
be any inefficient ?( was just thinking of other ways to do it
besides the standard ones you have suggested )
It would be more inefficient (at least with a naive processor) because
the processor would have to visit every child element of the current
node in order to count them. Node visits take time, so avoiding them
is a good idea. On the other hand, that's also the case with a naive
implementation of:
test="*"
However, most processors will rewrite this test to:
test="*[1]"
which only involves one node visit. I believe that Saxon rewrites
count(*) = 0 to boolean(*[1]) as well, actually, so perhaps there's
not much in it...
So try it and see with your favourite processor :)
Cheers,
Jeni
