sorting data and removing the duplicates

[Ronald <ronald at salience dot nl>]

Hi there,

I've encountered the following:

I have a huge list of variables being set ( it's a xml file)
and with XSLt i want to sort  this file on alfabetical order
and then remove the duplicates.
The xml file sort of looks like this:

<value><var>date1</var><date>01-01-1999</date></value>
<value><var>date2</var><date>01-02-1999</date></value>
<value><var>date3</var><date>01-01-1999</date></value>
<value><var>date2</var><date>01-02-1999</date></value>

I found that sorting this list was not so difficult, but removing the 
duplicates...erm...
I dunno how to do that with XSLT.
My current list looks like this:

<value><var>date1</var><date>01-01-1999</date></value>
<value><var>date2</var><date>01-02-1999</date></value>
<value><var>date2</var><date>01-02-1999</date></value>
<value><var>date3</var><date>01-01-1999</date></value>

But I want something that looks like:

<value><var>date1</var><date>01-01-1999</date></value>
<value><var>date2</var><date>01-02-1999</date></value>
<value><var>date3</var><date>01-01-1999</date></value>

BTW:
The content of the var. is enough to do a search on, F.E. date2 always gets 
the same value.

Can any of you help me out here?

Best regards
RH
