Subject:  Finding Unique Nodes


I have a list of items, many with duplicate values. I'd like to identify
only those that are unique.

For example:

<list>
 <item>Apple</item> 
 <item>Apple</item> 
 <item>Apple</item>
 <item>Apple</item>
 <item>Orange</item>
 <item>Pear</item> 
 <item>Pear</item>
 <item>Pear</item>
</list>


<xsl:value-of select="count(list/items)"/>

The above XML has 8 entries but I only want to tally those that are unique--
3.

Thanks for any help you can provide,

Greg
