I can suggest something like below (tested with IE 6.0):
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
version="1.0">
<xsl:output method="html" />
<xsl:key name="UNIQUE_ATTRS" match="ITEM" use="@ATTR" />
<xsl:key name="UNIQUE_ELEMS" match="ITEM" use="ELEM" />
<xsl:template match="/">
<xsl:call-template name="test">
<xsl:with-param name="theKey" select="'UNIQUE_ELEMS'"/>
<xsl:with-param name="theName" select="'ELEM'"/>
</xsl:call-template>
<xsl:call-template name="test">
<xsl:with-param name="theKey" select="'UNIQUE_ATTRS'"/>
<xsl:with-param name="theName" select="'ATTR'"/>
</xsl:call-template>
</xsl:template>
<xsl:template name="test">
<xsl:param name="theKey" select="." />
<xsl:param name="theName" select="." />
<p>
<xsl:value-of select="concat('key: ', $theKey)" /><br/>
<xsl:value-of select="concat('node: ', $theName)"/><br/>
<xsl:text>values:</xsl:text>
<xsl:variable name="rtf">
<xsl:for-each select="ROOT/ITEM[generate-id() =
generate-id(key($theKey, ELEM)[1])]">
<xsl:value-of select="." />
</xsl:for-each>
<xsl:for-each select="ROOT/ITEM[generate-id() =
generate-id(key($theKey, @ATTR)[1])]">
<xsl:value-of select="@ATTR" /><xsl:text> </xsl:text>
</xsl:for-each>
</xsl:variable>
<xsl:value-of select="msxsl:node-set($rtf)" />
</p>
</xsl:template>
</xsl:stylesheet>
It seems, it's difficult to make the stylesheet more generic than this.

I'm trying to write a generic function to output a list of unique values
on a selected node, whether it be an Element or Attribute. I've got the
Element portion working fine, but Attributes don't seem to want to run
through the for-each loop.... Here's a test which highlights this:
test.xml:
<?xml version="1.0" encoding="ISO8859-1" ?>
<?xml-stylesheet type="text/xsl" href="test.xsl"?>
<ROOT>
<ITEM ATTR="A1">
<ELEM>E1</ELEM>
</ITEM>
<ITEM ATTR="A1">
<ELEM>E1</ELEM>
</ITEM>
<ITEM ATTR="A2">
<ELEM>E2</ELEM>
</ITEM>
<ITEM ATTR="A2">
<ELEM>E2</ELEM>
</ITEM>
<ITEM ATTR="A3">
<ELEM>E3</ELEM>
</ITEM>
<ITEM ATTR="A3">
<ELEM>E3</ELEM>
</ITEM>
</ROOT>
test.xsl:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.0">
<xsl:output method="html" />
<xsl:key name="UNIQUE_ATTRS" match="ITEM" use="@ATTR" />
<xsl:key name="UNIQUE_ELEMS" match="ITEM" use="ELEM" />
<xsl:template match="/">
<xsl:call-template name="test">
<xsl:with-param name="theKey"
select="'UNIQUE_ELEMS'"/>
<xsl:with-param name="theName" select="'ELEM'"/>
</xsl:call-template>
<xsl:call-template name="test">
<xsl:with-param name="theKey"
select="'UNIQUE_ATTRS'"/>
<xsl:with-param name="theName" select="'ATTR'"/>
</xsl:call-template>
</xsl:template>
<xsl:template name="test">
<xsl:param name="theKey" select="." />
<xsl:param name="theName" select="." />
<p>
<xsl:value-of select="concat('key: ', $theKey)" /><br/>
<xsl:value-of select="concat('node: ', $theName)"
/><br/>
<xsl:text>values:</xsl:text>
<xsl:for-each select="ROOT/ITEM[ generate-id() =
generate-id( key( $theKey, *[local-name()=$theName] ) [1] ) ]">
<xsl:value-of select="." />
</xsl:for-each>
</p>
</xsl:template>
</xsl:stylesheet>
Opening "test.xml" returns:
key: UNIQUE_ELEMS
node: ELEM
values: E1 E2 E3
key: UNIQUE_ATTRS
node: ATTR
values:
Why is it that "A1 A2 A3" is not returned for the ATTR node? Is there
any way to write a generic for-each select expression that takes the
node name & key name and works for both elements and attributes? Any
help is greatly appreciated
Thanks,
