Conversion for multiqual - xslt

Question

I am trying to convert the following input XML based on grouping of qualifier but its not working and not giving me expected output.
Below is the Input XML which has to be comverted.
<document>
<item>
<gtin>1000909090</gtin>
<attrGroupMany name="foodAndBevPreparationInfo">
<row>
<attr name="preparationType">BOILING</attr>
<attrQualMany name="preparationInstructions">
<value qual="en">Prep 8</value>
<value qual="en">Prep 9</value>
<value qual="ar">Test</value>
</attrQualMany>
</row>
</attrGroupMany>
</item>
</document>
The XSLT which I am using but not giving me expected output.
XSLT:
<xsl:stylesheet
version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output indent="yes"/>
<xsl:key name="prepmvl" match="preparationInstructions" use="concat(generate-id(..), '|', #qual)" />
<xsl:template match="document">
<CatalogItem>
<RelationshipData>
<xsl:for-each select="item/attrGroupMany[#name ='foodAndBevPreparationInfo']/row">
<Relationship>
<RelationType>Item_Master_Food_And_Bev_Prep_MVL</RelationType>
<RelatedItems count="{count(attrQualMany[#name='preparationInstructions']/value[generate-id() = generate-id(key('prepmvl', concat(generate-id(..), '|', #qual))[1])])}">
<xsl:apply-templates select="attrQualMany[#name='preparationInstructions']/value[generate-id() = generate-id(key('prepmvl', concat(generate-id(..), '|', #qual))[1])]"/>
</RelatedItems>
</Relationship>
</xsl:for-each>
</RelationshipData>
</CatalogItem>
</xsl:template>
<xsl:template match="preparationInstructions">
<RelatedItem1 referenceKey="{concat('Food_And_Bev_Prep_MVL','-',ancestor::item/gtin,'-',attr[#name='preparationType'],'-',#qual)}"/>
</xsl:template>
</xsl:stylesheet>
And the expected output should be
<?xml version="1.0" encoding="UTF-8"?>
<CatalogItem>
<RelationshipData>
<Relationship>
<RelationType>Item_Master_Food_And_Bev_Prep_MVL</RelationType>
<RelatedItems count="2">
<RelatedItem1 referenceKey="Food_And_Bev_Prep_MVL-1000909090-BOILING-en" />
<RelatedItem1 referenceKey="Food_And_Bev_Prep_MVL-1000909090-BOILING-ar" />
</RelatedItems>
</Relationship>
</RelationshipData>
</CatalogItem>

Answer 1

you need to change
<xsl:key name="prepmvl" match="preparationInstructions" use="concat(generate-id(..), '|', #qual)" />
to
<xsl:key name="prepmvl" match="value" use="concat(generate-id(..), '|', #qual)" />
and
<xsl:template match="preparationInstructions">
<RelatedItem1 referenceKey="{concat('Food_And_Bev_Prep_MVL','-',ancestor::item/gtin,'-',attr[#name='preparationType'],'-',#qual)}"/>
</xsl:template>
to
<xsl:template match="value">
<RelatedItem1 referenceKey="{concat('Food_And_Bev_Prep_MVL','-',ancestor::item/gtin,'-',../preceding-sibling::attr[#name='preparationType'],'-',#qual)}"/>
</xsl:template>
