This is a grouping question, and if you hear people groaning it's because
these seem to arise repeatedly :-) Please see Jeni Tennison's site for
descriptions on a couple different ways to do this--at least one of them,
the Meunchian Method, is efficient and performant: www.jenitennison.com
The archives for this list is here:
http://www.biglist.com/lists/xsl-list/archives/ . It's searchable, and I'm
sure you'll find many references to grouping.
The following is a site that culls topics of interest from this ng:

Subject: [xsl] selecting unique entries from a list
Date: Thu, 5 May 2005 11:14:35 +0100
Dear all,
Hope you can help with this query. I am new to XML/XSLT.
I need to take the following XML and generate an initial web page
displaying only one instance of
each department name.
<xml>
<List>
<Entry>
<Session>2004/5</Session>
<Department>Accounting and Finance</Department>
</Entry>
<Entry>
<Session>2004/5</Session>
<Department>Accounting and Finance</Department>
</Entry>
<Entry>
<Session>2004/5</Session>
<Department>Maths</Department>
</Entry>
<Entry>
<Session>2004/5</Session>
<Department>Maths</Department>
</Entry>
<Entry>
<Session>2004/5</Session>
<Department>Economic History</Department>
</Entry>
</List>
</xml>
so in the html only unique departments would be displayed once:
Accounting and Finance
Maths
Economic History
What's the best way to do this in xslt?
I understand that I can filter on specific names within the xslt and do
conditional
tests but I do not want to have to change the xslt each time if the
departments in the xml change.
Hope it makes sense.
Regards,
Mike
