RE: [xsl] MSXML ancestor-or-self

[Richard Mitchell <Richard.Mitchell@xxxxxxxxxxxxx>]

First of all thanks Chris...

Ok my example is a bit poor sorry for that but really my context is
C with a file like...

<A>
 	<P name="hello" value="blue"/>
	<P name="aval" value="uppest"/>
	<B>
		<P name="bval" value="upper"/>
		<P name="goodbye" value="red"/>
		<P name="hello" value="green"/>
		<C>
			<P name="goodbye" value="yellow"/>
		</C>
		<P name="goodbye" value="orange"/>
	</B>
</A>

Expecting output like...
;goodbye=yellow;hello=green;bval=upper;hello=uppest

I've just experimented a little with the | operator but can't get
anything sensible out of it
