RE: RE: Using not(...a nd ... ) to select nodes

So what you are asking for is an XPath expression that will select all the unique <item> nodes (as distinguished by the values of their child nodes), correct?

Here is an XML document based on my understanding of your question:
Based on this, you want an expression which returns the first, second, and third <item> nodes, and not the fourth and fifth because they are identical to one of the first three. Is that right?

<?xml version="1.0" encoding="UTF-8" ?>
<items>
  <item>
    <name>truck</name>
    <type>silverado</type>
    <status>on</status>
  </item>
  <item>
    <name>truck</name>
    <type>silverado</type>
    <status>off</status>
  </item>
  <item>
    <name>truck</name>
    <type>ranger</type>
    <status>on</status>
  </item>
  <item>
    <name>truck</name>
    <type>silverado</type>
    <status>on</status>
  </item>
  <item>
    <name>truck</name>
    <type>silverado</type>
    <status>off</status>
  </item>
</items>

I'm sorry, I wasn't thinking/typing clearly.  There's three that are of
concern.  There are actually more, but I need to select nodes based on
those three.
