RE: [xsl] Searching in Sub-children from an Array

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::*[(_at_)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::*[(_at_)ID]/@ID,',')),.)[*]
"/>


Any comments please?  

Many Thanks,
Houman
