Hi Nathan,
I cant completely write your XSL. infact I havent even looked at your XSL
code.
What I have done will take you in the direction ...
I have written an xsl that will eliminate duplicate
<xcal:vevent>
with the same <obprcal:eventid> value
in other words, if there are more than one
<xcal:vevent> with the same value for <obprcal:eventid>,
then only one of them will be selected.
Following is the code...
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:obprcal="http://spaceresearch.nasa.gov/calendar";
xmlns:xcal="http://www.ietf.org/internet-drafts/draft-ietf-calsch-many-xcal-
01.txt" xmlns="http://spaceresearch.nasa.gov/calendar";>
<xsl:key match="/obprcal:top/xcal:vcalendar/xcal:vevent" name="events"
use="obprcal:eventid"/>
<xsl:template match="/">
<!-- get unioe-nodes -->
<xsl:for-each
select="/obprcal:top/xcal:vcalendar/xcal:vevent[generate-id(.) =
generate-id(key('events',obprcal:eventid)[1])]">
<xsl:sort order="ascending" data-type="number" select="obprcal:eventid"/>
<xsl:value-of select="obprcal:eventid"/>
<!--
you can add your code here,, I have just printed the value of
obprcal:eventid, so that you see the result ..
-->
<br/>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
First Run this xsl as is against your XML and see if you are happy ..
Let me know if thaz not what you want
Hope this helps

Subject: [xsl] grouping and discarding duplicates
Hi all. I have an XSLT that sorts and groups on date
per category. However, the client has changed the
specs and now wants multiple categories and an All
Categories page. This means that I have to shed
duplicate events that appear in different categories
and group the categories for display. I have spent a
day and a half trying to figure out how to do this
without much luck.
What I want to end up with is a record like this:
<DataTableRow>
<DataTableRowCell><strong>HOLIDAY - Labor
Day</strong></DataTableRowCell>
</DataTableRow>
<DataTableRow>
<DataTableRowCell>September 06, 2004 08:00
AM-September 06, 2004 05:00 PM (All
Day)</DataTableRowCell>
</DataTableRow>
<DataTableRow>
<DataTableRowCell>Categories: Education Events,
External Technical Meetings, General Interest, Public
Outreach Events, Industry</DataTableRowCell>
<DataTableRow>
<DataTableRowCell> </DataTableRowCell>
</DataTableRow>
Can someone lend a hand? The XML and XSLT files are
too large to include, but can be downloaded here, in
the XML-XSLT folder:

Thanks a bunch in advance!
