Taking help from Abel's ideas, I find this solution nice:
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="2.0">
<xsl:output method="xml" indent="yes" />
<xsl:template match="x">
<x>
<xsl:for-each select="edge[not(some $i in preceding-sibling::edge
satisfies deep-equal($i, .))]">
<xsl:copy-of select="." />
</xsl:for-each>
</x>
</xsl:template>
</xsl:stylesheet>
This when applied to the XML:
<x>
<edge source="IGetter" target="CGetter" dependency="positive"/>
<edge source="IGetter" target="CGetter" dependency="positive"/>
<edge source="IGetter" target="CCount" dependency="positive"/>
<edge source="ICount" target="IGetter" dependency="positive"/>
<edge source="ICount" target="CGetter" dependency="positive"/>
<edge source="ICount" target="ICount" dependency="positive"/>
<edge source="ICount" target="CCount" dependency="positive"/>
<edge source="ICount" target="CCount" dependency="positive"/>
</x>
Produces output:
<?xml version="1.0" encoding="UTF-8"?>
<x>
<edge source="IGetter" target="CGetter" dependency="positive"/>
<edge source="IGetter" target="CCount" dependency="positive"/>
<edge source="ICount" target="IGetter" dependency="positive"/>
<edge source="ICount" target="CGetter" dependency="positive"/>
<edge source="ICount" target="ICount" dependency="positive"/>
<edge source="ICount" target="CCount" dependency="positive"/>
</x>

Hello,
I am wondering what's the best way of getting rid of duplicate nodes
which contain more than one attribute. Suppose I have den following xml:
<edge source="IGetter" target="CGetter" dependency="positive"/>
<edge source="IGetter" target="CGetter" dependency="positive"/>
<edge source="IGetter" target="CCount" dependency="positive"/>
<edge source="ICount" target="IGetter" dependency="positive"/>
<edge source="ICount" target="CGetter" dependency="positive"/>
<edge source="ICount" target="ICount" dependency="positive"/>
<edge source="ICount" target="CCount" dependency="positive"/>
<edge source="ICount" target="CCount" dependency="positive"/>
How do I get rid of one
<edge source="IGetter" target="CGetter" dependency="positive"/>
and one
<edge source="ICount" target="CCount" dependency="positive"/>
which appear twice?
If there was only one attribute, lets say "source" it would be simple:
<xsl:for-each
select="//edge[not(./@source=preceding-sibling::edge/@source)]">
<xsl:copy-of select="."/>
</xsl:for-each>
So I thought with more attributes this would work:
<xsl:for-each select="//edge[not(./@source=preceding-sibling::edge/@source
and ./@target=preceding-sibling::edge/@target
and ./@dependency=preceding-sibling::edge/@dependency
)]">
</xsl:for-each>
But of course it doesen't because in one iterartion the
"preceding-siblings" doesn't point to the same element.
So, any help would be appreciated on how to get rid of duplicates.

Garvin
