Hello,

May I rephrase my question, please?


XML Input:

<tree>
	<fruit ID="111">
		<mango ID="333">
			<colour>
				<Rate_Structure_Event>
					<Rate ConceptType="Rate_Event">

<Added_Unit_Rate>909000</Added_Unit_Rate>
					</Rate>
					<Rate ConceptType="Rate_Event">

<Added_Unit_Rate>889000</Added_Unit_Rate>
					</Rate>
				</Rate_Structure_Event>
			</colour>
		</mango>
		<orange ID="222">
			<color>orange</color>
		</orange>
	</fruit>
	<fruit_adjustment>
		<color>
			<Path>
				<Steps>111,333</Steps>
			</Path>
			<Rate_Event ConceptType="Rate_Event">
				<Added_Unit_Rate>3000</Added_Unit_Rate>
			</Rate_Event>
			<Rate_Event ConceptType="Rate_Event">
				<Added_Unit_Rate>2000</Added_Unit_Rate>
			</Rate_Event>
		</color>
	</fruit_adjustment>
</tree>




XSLT 2.0:

<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

	<xsl:key name="step" match="fruit_adjustment/color//Rate_Event"
use="../Path/Steps"/>

	<xsl:template match="*">
		<xsl:copy>
			<xsl:copy-of select="@*"/>
			<xsl:apply-templates/>
		</xsl:copy>
	</xsl:template>

	<xsl:template match="fruit_adjustment"/>

	<xsl:template match="colour">
		<xsl:copy-of
select="(key('step',string-join(ancestor-or-self::*[@ID]/@ID,',')),.)[*]
"/>
	</xsl:template>

</xsl:stylesheet>



Expected Output:

<tree>
	<fruit ID="111">
		<mango ID="333">
			<colour>
				<Rate_Structure_Event
ConceptType="Rate_Structure_Event"
ID="23b6128e-b622-4fa9-983b-95349bed5d41">
					<Rate_Event
ConceptType="Rate_Event">

<Added_Unit_Rate>3000</Added_Unit_Rate>
					</Rate_Event>
					<Rate_Event
ConceptType="Rate_Event">

<Added_Unit_Rate>2000</Added_Unit_Rate>
					</Rate_Event>
				</Rate_Structure_Event>
			</colour>
		</mango>
		<orange ID="222">
			<color>orange</color>
		</orange>
	</fruit>
</tree>



However I get this output:
<tree>
	<fruit ID="111">
		<mango ID="333">
			<Rate_Event ConceptType="Rate_Event">
				<Added_Unit_Rate>3000</Added_Unit_Rate>
			</Rate_Event>
			<Rate_Event ConceptType="Rate_Event">
				<Added_Unit_Rate>2000</Added_Unit_Rate>
			</Rate_Event>
			<colour>
				<Rate_Structure_Event
ConceptType="Rate_Structure_Event"
ID="23b6128e-b622-4fa9-983b-95349bed5d41">
					<Rate ConceptType="Rate_Event">

<Added_Unit_Rate>909000</Added_Unit_Rate>
					</Rate>
					<Rate ConceptType="Rate_Event">

<Added_Unit_Rate>909000</Added_Unit_Rate>
					</Rate>
				</Rate_Structure_Event>
			</colour>
		</mango>
		<orange ID="222">
			<color>orange</color>
		</orange>
	</fruit>
</tree>


Why are the elements copied outside the <colour>?

I think the problem lies in <xsl:copy-of
select="(key('step',string-join(ancestor-or-self::*[@ID]/@ID,',')),.)[*]
"/>


Any comments please?

Many Thanks,
