RE: Grouping into duplicates and non duplicate lists

Hi David,

Thanks for that. I have put it together and it works!! It does not look too
elegant and I need to use 2 keys to do what I want. Here is the template if
anyone has any suggestions for improving - happy to take on board... Thanks
again:

<xsl:template match="CourseNote">
		<xsl:variable name="sgcount" select="count(CourseNoteItem[count(. |
key('CN-SG', concat(Year, StudyGroupCode))[1]) = 1])" />
		<xsl:if test="CourseNoteItem[count(. | key('CN-T', concat(Year,
CourseNoteText))[1]) = 1][count(key('CN-T', concat(Year,
CourseNoteText)))=$sgcount]">
			<strong>Applies to all Study Groups</strong>
			<br />
			<ul>
				<xsl:for-each select="CourseNoteItem[count(. | key('CN-T', concat(Year,
CourseNoteText))[1]) = 1][count(key('CN-T', concat(Year,
CourseNoteText)))=$sgcount]">
					<xsl:sort select="DisplaySequence" />
					<li>
						<xsl:copy-of select="CourseNoteText/node()" />
					</li>
				</xsl:for-each>
			</ul>
		</xsl:if>
		<xsl:for-each select="CourseNoteItem[count(. | key('CN-SG', concat(Year,
StudyGroupCode))[1]) = 1]">
			<xsl:sort select="StudyGroupOrder" />
			<xsl:if test="key('CN-SG', concat(Year, StudyGroupCode))[count(key('CN-T',
concat(Year, CourseNoteText)))!=$sgcount]">
				<strong>
					<xsl:value-of select="StudyGroupName" /> - Only</strong>
				<br />
				<ul>
					<xsl:for-each select="key('CN-SG', concat(Year,
StudyGroupCode))[count(key('CN-T', concat(Year,
CourseNoteText)))!=$sgcount]">
						<li>
							<xsl:copy-of select="CourseNoteText/node()" />
						</li>
					</xsl:for-each>
				</ul>
			</xsl:if>
		</xsl:for-each>
	</xsl:template>

not looked in detail at your example, just perhaps just answering this
bit iis enough

>  StudyGroups...

one way

<xsl:key name="sg" match="studyroup" use="item"/>

then <xsl:variable name="n" select="count(studygroup)"/>

so to know if . the current item is in all groups you can test
count(key('sg',.))=$n
as if it is in all groups then the key will return them all

David
