Re: New twist: eliminating nodes with duplicate content, case-ins ensi tive

["Richman, Jeremy" <jrichman@xxxxxxxxxxxx>]

My question is really how to eliminate duplicates, counting
   <handle>FOO</handle>
and
   <handle>foo</handle>
as duplicates.

I still need an answer, if anyone knows one.

<xsl:variable "unique-handles" select="//handle[not( self::node() =
following::handle )]"/>

In the above case, this variable would resolve to a node list of
two nodes.

How can I generate only one foo element in the output?

(This is a simple example; my general problem includes other values,
such as "bar", "BAR", also in the node list.)

Jeremey,

  Use the translate function:  translate(source,'ABC...Z','abc...z')
