Chris,

Try

select="items/item[not(preceding-sibling::*
  [name=current()/name and
   type = current()/type and
  status = current()/status])]"

The problem with your statement is it's testing true if there no corresponding values on any preceding siblings, whereas you want it to be true only if there's a preceding sibling with all corresponding values.

I hope that works for you--

Cheers,
Wendell

I'm trying to create a node set that only contains different nodes.  The
problem I'm running into is I seem to be losing nodes that I shouldn't.

I'm using the following to select the nodes:

<xsl:for-each select="items/item[not(name = preceding-sibling::*/name
and type = preceding-sibling::*/type and status =
preceding-sibling::*/status)]">


An example from the XML might be: truck,silverado,chevy,on
truck,silverado,chevy,off truck,ranger,ford,on  truck,silverado,chevy,on
truck,silverado,chevy,off

I'm getting are the second and third ones.

Any suggestions would be much appreciated.
