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
