Hi Jonathan,
I think you need this stylesheet! As Mike suggested
we need to use Muenchian grouping technique..
<?xml version="1.0"?>
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.0">
<xsl:output method="text" />
<xsl:key name="by-elem" match="a/* | c/*" use="." />
<xsl:template match="/root">
<xsl:for-each select="(a/* | c/*)[generate-id() =
generate-id(key('by-elem',.)[1])][count(key('by-elem',.))
= 1]">
<xsl:value-of select="."
/><xsl:text>
</xsl:text>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
Regards,
Mukul

Ok, I kind of got your point thus far. In my
example,
I had two parents, 'a' and 'c'. How would I go
about
outputing what is in 'a' and not 'c' separately from
outputing what is in 'c' but not 'a'. In other
words,
I want to run my XSL to account for both the unique
values in 'a' as well as the unique values in 'c'.

Read about Muenchian grouping at

You can use the same idea to test whether a value
is
unique within the file
(a member of a group of one) by defining the
grouping key
<xsl:key name="gk" match="b|bb|bbb" use="."/>
and testing a node
<xsl:template match="b|bb|bbb">
<xsl:if test="not(key('gk', .)[2])">
The value is unique
</xsl:if>
</xsl:template>

Subject: [xsl] Outputing a node whose value
appears only once
What I would like to do now is output a value
that
appears only once throughout the XML file. For
example, if I have:
<a>
<b>value1</b>
<bb>value2</bb>
<bbb>value3</bbb>
</a>
<c>
<b>value1</b>
<bb>value2</bb>
<bbb>value4</bbb>
</c>
From the point of view of 'a', I would want to
output
"value3" because 'a' contains it but 'c' does
not.
This is assuming that the above is the entire
file. I
also need to output a sibling of the node which
does
not appear more than once (like the value of a/b
or
a/bbb). It is also assumed that multiple
instances of
the same value will have different parents.
This
is
shown in the example above.
Thanks for the help.
Jonathan
