Subject: [xsl] 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
