Thanks David A littlemore cleaner way was to use XSLT transformation. I was just interested in knowing if there is any provisions in Camel itself. Was trying to explore if idempotent consumer can work with more than 1 parameters as identifier.
Following XSL code did the magic! *<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";> <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/> <xsl:key name="currencyPair" match="Rate" use="concat(SourceCurrency,' ',TargetCurrency)"/> <xsl:template match="ExchangeRates"> <xsl:copy> <xsl:for-each select="Rate[count(. | key('currencyPair',concat(SourceCurrency,' ',TargetCurrency))[1]) = 1]"> <xsl:copy-of select="."/> </xsl:for-each> </xsl:copy> </xsl:template> </xsl:stylesheet> * Cheers Reji -- View this message in context: http://camel.465427.n5.nabble.com/Duplicate-Elimination-tp5760020p5760047.html Sent from the Camel - Users mailing list archive at Nabble.com.
