RE: [xsl] document() merge DISTINCT

["Chris Bayes" <chris@xxxxxxxxxxx>]

Alex,
Something like this should do it
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
	<xsl:param name="file" />
	<xsl:template match="/">	
		<xsl:apply-templates select="/p/project" />
		<xsl:copy-of select="document($file)/p/project[not(@name
= current()/p/project/@name)]" />
	</xsl:template>
	<xsl:template match="project">
		<xsl:copy>
			<xsl:copy-of select="@*|*" />
			<xsl:copy-of
select="document($file)/p/project[@name =
current()/@name]/person[not(@id = current()/person/@id)]" />
		</xsl:copy>
	</xsl:template>
</xsl:stylesheet>

Ciao Chris
