OK, Subject is odd, but I didn't know how to be descriptive of my problem in the allocated space.

First, I'm using Saxon8B.

What I want to do is create an index of values for a specific node type.

So I have an XML document that has many <ItemName> nodes. Almost all of them have repeated values. I may have 20 with the value of 'Car', 30 with a value of 'Radio', 10 with a value of 'Pencil'.. you get the idea.

I want to create a result set that has each of these names, but only once. Basically a list of unique items. So:

Car
Radio
Pencil

not

Car
Car
Car
..
Car
Radio
Radio
..
Radio
Pencil
Pencil
..
Pencil


Any Ideas?

You'll want to use the XPATH 2.0 function distinct-values(), e.g. <xsl:sequence select="distinct-values(ItemName)">

That's what I was looking for..

If you just want the values, use the distinct-values() function.

If you want to process the groups of elements that share a value in common, use xsl:for-each-group.

Both these features are new in XSLT 2.0.

I was just about to look into xsl:for-each-group when Sam suggested distinct-values().
For now, I just want the list of values, so the function is working fine.

Thanks for all the help!
