RE: [xsl] MSXML ancestor-or-self

["Chris Bayes" <Chris at Bayes dot co dot uk>]

Mitchel,
In that case you want all child nodes P
select="P"
and all preceding nodes P that don't have a preceding P with the same name
and don't have a name the same as any child nodes P of the current node.

select="P|preceding::P[@name != preceding::P/@name and @name !=
current()/P/@name]"

this doesn't work if your xml looks like this

<A>
	<P name="hello" value="blue"/>
	<P name="goodbye" value="redish"/>
	<P name="welcome" value="silver"/>
	<B>
		<P name="goodbye" value="red"/>
		<P name="hello" value="green"/>
		<C/>
	</B>
	<B>
		<P name="welcome" value="orange"/>
		<P name="hello" value="purple"/>
		<C/>
	</B>
</A>

Ciao Chris
