RE: [xsl] optional children

["Andrew Welch" <awelch@xxxxxxxxxxxxxxx>]

Oleg:
<xsl:template match="a[count(b|c|d) = count(*)]">
	<foo/>
</xsl:template>

ahhh very nice, I had been trying to come up with a count() based
solution and failing - this looks like the one though.

Jeni:
<xsl:if test="b and not(*[not(self::c or self::d)])">
  <foo />
</xsl:if>

Ok so here you are using not() within a not() to exclude nodes from the
list of excluded nodes... this doesnt work for me but I get the logic
behind it.  Does it fail because not(*[...]) will evaluate to false
before it even gets to the predicates (because <b> must exist already)??
Or will the first predicate always be evaluated if there is one?

cheers
