Or, I suppose, you could include what weve been seeing on the other
thread and use normalize-space() to bypass whitespace-only nodes:
beware though that node()[normalize-space()] doesn't just skip past
white space text nodes, it skips past any node with zero length string
value, so if you are on <a/> in
<x>
<a/></b/></c><!-- hello-->
</x>
<xsl:if
test="preceding-sibling::node()[normalize-space()][1][self::comment()]">
is true.
