BizTalk XSLT Mapping For Grouping and Sorting with Multiple Records - xslt

Question

Input Message :
The Input File Has Three Records inside the Detail is in the order “Member” , “Product” and “Dependent” , In each Record there is a common Field which is “ Identifier” For Some reason we getting like Each Member and Product are looped into one detail and Each dependent is looping into separate Detail

Expected OutPut XML :
The OutPut File is also Similar to the Input File but the order is “Member” , “Dependent” and “Product” . The Common Field “Identifier” is the common on in this case also.The idea is to make Detail to loop on “Member” , “Dependent” and “Product” order.

Need Suggestion on writing XSLT 1.0 Code for this.

Answer 1

You can do this in XSLT-1.0 with Muenchian Grouping. Search for it on StackOverflow and you will find a lot of examples. Applying it created the following answer:
Create an xsl:key with the nodes Member|Dependent|Product using its Identifier element value as a key
Create a sortingOrder variable which provides indices for sorting the entries in the inner xsl:for-each
Match and copy the root node /ns0:Root with a template
Loop over all children of the Detail elements in a xsl:for-each. The expression applies the Muenchian Grouping method
Create a Detail elements and loop over the results of the previous xsl:for-each sorted by the index of the occurrence of the name of the current element in the sortingOrder variable. Copy its content. The method of ordering the elements was taken from this SO answer: "Sorting XML in XSLT based on a list of values".
The stylesheet could look like this:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:ns0="Test">
<xsl:output indent="yes"/>
<xsl:key name="id" match="Member|Dependent|Product" use="Identifier" />
<xsl:variable name="sortingOrder" select="'Member,Dependent,Product'" />
<xsl:template match="/ns0:Root">
<xsl:copy>
<xsl:for-each select="Detail/*[generate-id() = generate-id(key('id',Identifier)[1])]">
<Detail>
<xsl:for-each select="key('id',Identifier)">
<xsl:sort data-type="number" select="string-length(substring-before($sortingOrder,local-name()))" />
<xsl:copy-of select="."/>
</xsl:for-each>
</Detail>
</xsl:for-each>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
The output should be as desired.
