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.
