Re: [xsl] Duplicate Elimination

[Martin Holmes <mholmes@xxxxxxx>]

If the text content of the element is all you care about, you could do 
something like this:

<xsl:variable name="distinctDates">
<xsl:for-each select="distinct-values(A/Date | B/Date)">
	<xsl:sort/>
	<Date><xsl:value-of select="."/></Date>
</xsl:for-each>
</xsl:variable>

<xsl:apply-templates select="$distinctDates/Date"/>
