sorting dates in XML using xslt - xslt-1.0

I want to sort the dates in xml using xslt and my date element is validated in xsd with datatype as date below is my xml and xsl
XML
<Trade xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

</Symbol>
</Trade>
XSD
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template name="fiExoticStructuredDeal">
<fixedIncomeExoticDeal>
<frontOfficeDealDescription>Empty decription</frontOfficeDealDescription>
<component>
<frontOfficeComponentType>
<optionDetails>
<optionStyle>European</optionStyle>
<optionDates>
<adjustedDate>
<xsl:for-each select="/Trade/Symbol/Economic/Leg/Schedule">
<xsl:sort select="concat(substring-before(Date,'-'), substring-before(substring-after(Date,'- '),'-'),substring-after(substring-after(Date,'-'),'-'))" order="ascending"/>
<xsl:choose>
<xsl:when test="position() = last()">
<xsl:value-of select="Date"/>
</xsl:when>
</xsl:choose>
</xsl:for-each>
</adjustedDate>
</optionDates>
</optionDetails>
</frontOfficeComponentType>
</component>
</fixedIncomeExoticDeal>
</xsl:template>
</xsl:stylesheet>
I am not able sort the Date using xslt.It always gives me the last date in Schedule element.
It will be great if someone let me know if i am missing something.


Use
<xsl:sort select="Date" order="ascending"/>

Advanced muenchian grouping: group by items in child collection

I'm familiar with simple muenchian grouping in XSL, but I've encountered a problem, which I honestly don't even know, how to approach it.
So I've got an XML:
<whiskies>
<whisky name="ABC" percent="" region="" type="">
<tastingNotesCollection/>
<bottles>
<bottle price="" size="" level="0" date=""/>
<bottle price="" size="" level="70" date=""/>
<bottle price="" size="" level="100" date=""/>
</bottles>
<comments/>
</whisky>
<whisky name="DEF" percent="" region="" type="">
<tastingNotesCollection/>
<bottles>
<bottle price="" size="" level="0" date=""/>
<bottle price="" size="" level="100" date=""/>
</bottles>
<comments/>
</whisky>
<whisky name="GHI" percent="" region="" type="">
<tastingNotesCollection/>
<bottles>
<bottle price="" size="" level="30" date=""/>
</bottles>
<comments/>
</whisky>
<whiskies>
And the goal is to group the whiskies by levels of a bottle:
So level="0" is considered empty.
Anything from level="1" to level="99" is considered open.
And level="100" is considered unopened.
So the transformed result (will be done in HTML) should look like this:
<h1>Empty</h1>
<ul>
<li>ABC</li>
<li>DEF</li>
</ul>
<h1>Open</h1>
<ul>
<li>ABC</li>
<li>GHI</li>
</ul>
<h1>Unopened</h1>
<ul>
<li>ABC</li>
<li>DEF</li>
</ul>
As you can see, the same whisky can show up in multiple groups, depending on how much bottles there are and how full those bottles are.
The second problem is, that the "Open" group doesn't have an exact value and can be aynthing from 1 to 99.
So yeah, don't really know if this can be solved at all or how to even start on this. Any tips appreciated.

I don't think you want to use Muenchian grouping for this. You would need to define a key that enumerates all values in the range from 1 to 99 - and I believe that would take away any advantage that using a key would otherwise bring.
Since your result has either exactly or at most 3 groups (your question is ambiguous in this respect), you could do simply:
XSLT 1.0
<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:template match="/whiskies">
<output>
<group status="empty">
<xsl:for-each select="whisky[bottles/bottle/#level=0]">
<name>
<xsl:value-of select="#name"/>
</name>
</xsl:for-each>
</group>
<group status="open">
<xsl:for-each select="whisky[bottles/bottle[#level>0 and #level < 100]]">
<name>
<xsl:value-of select="#name"/>
</name>
</xsl:for-each>
</group>
<group status="unopened">
<xsl:for-each select="whisky[bottles/bottle/#level=100]">
<name>
<xsl:value-of select="#name"/>
</name>
</xsl:for-each>
</group>
</output>
</xsl:template>
</xsl:stylesheet>
to get (after fixing the input to be a well-formed XML!):
Result
<?xml version="1.0" encoding="utf-8"?>
<output>
<group status="empty">
<name>ABC</name>
<name>DEF</name>
</group>
<group status="open">
<name>ABC</name>
<name>GHI</name>
</group>
<group status="unopened">
<name>ABC</name>
<name>DEF</name>
</group>
</output>
Make your own adjustment for HTML output.
Added:
Here is an alternative approach using keys (though still not Muenchian grouping) which might be more performant:
<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="w" match="whisky" use="bottles/bottle/#level" />
<xsl:key name="w1" match="whisky" use="boolean(bottles/bottle[#level!=0 and #level!=100])" />
<xsl:template match="/whiskies">
<output>
<group status="empty">
<xsl:for-each select="key('w', 0)">
<name>
<xsl:value-of select="#name"/>
</name>
</xsl:for-each>
</group>
<group status="open">
<xsl:for-each select="key('w1', true())">
<name>
<xsl:value-of select="#name"/>
</name>
</xsl:for-each>
</group>
<group status="unopened">
<xsl:for-each select="key('w', 100)">
<name>
<xsl:value-of select="#name"/>
</name>
</xsl:for-each>
</group>
</output>
</xsl:template>
</xsl:stylesheet>
Or even:
<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="bottle" match="bottle" use="ceiling(#level div 99)" />
<xsl:template match="/whiskies">
<output>
<group status="empty">
<xsl:for-each select="key('bottle', 0)/../..">
<name>
<xsl:value-of select="#name"/>
</name>
</xsl:for-each>
</group>
<group status="open">
<xsl:for-each select="key('bottle', 1)/../..">
<name>
<xsl:value-of select="#name"/>
</name>
</xsl:for-each>
</group>
<group status="unopened">
<xsl:for-each select="key('bottle', 2)/../..">
<name>
<xsl:value-of select="#name"/>
</name>
</xsl:for-each>
</group>
</output>
</xsl:template>
</xsl:stylesheet>

If you did want to use xsl:key, you could create 3 of them with the filter criteria:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output indent="yes" />
<xsl:key name="Empty" match="whisky[bottles/bottle/#level=0]" use="#name"/>
<xsl:key name="Open" match="whisky[bottles/bottle/#level[. > 1 and . < 99]]" use="#name"/>
<xsl:key name="Unopened" match="whisky[bottles/bottle/#level=100]" use="#name"/>
<xsl:template match="/">
<xsl:variable name="whiskies" select="/whiskies/whisky/#name"/>
<xsl:for-each select="document('')/xsl:stylesheet/xsl:key/#name">
<xsl:variable name="status" select="."/>
<h1><xsl:value-of select="$status"/></h1>
<ul>
<xsl:for-each select="$whiskies[key($status, .)]">
<li><xsl:value-of select="."/></li>
</xsl:for-each>
</ul>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>

Custom XSLT Tag

I am sick of write all the call-template/with-param stuff.
Is there any shortcut for this in example:
<xsl:call-template name="complexwidget">
<xsl:with-param name="a" select="$bla_213"/>
<xsl:with-param name="b" select="$bla_213"/>
<xsl:with-param name="c" select="$bla_213"/>
<xsl:with-param name="d" select="$bla_213"/>
</xsl:call-template>
A Perfect posibility would be this:
<complex a="{$bla_213}" b="{$bla_213}" c="{$bla_213}" d="{$bla_213}" />
Any idea, maybe a twice-transform-xslt??

If you could switch to xslt 2.0 then user functions would be exactly what you need.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:fn="http://www.w3.org/2005/xpath-functions" xmlns:my="my-namespace">
<xsl:output method="text" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="/">
<xsl:value-of select="my:complexWidget(1, 2, 3, 4)" />
</xsl:template>
<xsl:function name="my:complexWidget">
<xsl:param name="a" />
<xsl:param name="b" />
<xsl:param name="c" />
<xsl:param name="d" />
<!-- Do something -->
<xsl:value-of select="($a, $b,$c, $d)" separator="-" />
</xsl:function>
</xsl:stylesheet>
In xslt 1.0 I think that preprocessing of xslt stylesheet with another transformation will be the only way (or may be writing some extension functions in language of your processor .
EDIT:
I tried the "preprocess" of xslt and it seems to be working (but probably it is no the most elegant way how to do it).
Input xslt
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:mypp="my-preprocess-namespace">
<xsl:output method="text" />
<xsl:template match="/">
<xsl:variable name="varA" select="1"/>
<xsl:variable name="varB" select="2"/>
<xsl:variable name="varC" select="3"/>
<xsl:variable name="varD" select="4"/>
<mypp:complexWidget a="$varA" b="$varB" c="$varC" d="$varD"/>
</xsl:template>
<xsl:template name="complexWidget">
<xsl:param name="a"/>
<xsl:param name="b"/>
<xsl:param name="c"/>
<xsl:param name="d"/>
<!-- do something-->
<xsl:value-of select="$a"/>
<xsl:text>-</xsl:text>
<xsl:value-of select="$b"/>
<xsl:text>-</xsl:text>
<xsl:value-of select="$c"/>
<xsl:text>-</xsl:text>
<xsl:value-of select="$d"/>
</xsl:template>
</xsl:stylesheet>
I defined here a special namespace for element to be replaced (i.e. xmlns:mypp="my-preprocess-namespace"). Element to be replaced is <mypp:complexWidget a="$varA" b="$varB" c="$varC" d="$varD"/>.
This xslt I preprocess with following xslt.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:mypp="my-preprocess-namespace">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="node() | #*">
<xsl:copy>
<xsl:apply-templates select="node() | #*" />
</xsl:copy>
</xsl:template>
<xsl:template match="mypp:*">
<xsl:element name="xsl:call-template">
<xsl:attribute name="name">
<xsl:value-of select="local-name()" />
</xsl:attribute>
<xsl:for-each select="#*">
<xsl:element name="xsl:with-param">
<xsl:attribute name="name">
<xsl:value-of select="name()" />
</xsl:attribute>
<xsl:attribute name="select">
<xsl:value-of select="." />
</xsl:attribute>
</xsl:element>
</xsl:for-each>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
It is based on "Identity transform" - copy everything to the output just elements from special namespace transform into the call-template element. I guess this could be done in more nice way than I did.
The output is
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:mypp="my-preprocess-namespace" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="text" />
<xsl:template match="/">
<xsl:variable name="varA" select="1"/>
<xsl:variable name="varB" select="2"/>
<xsl:variable name="varC" select="3"/>
<xsl:variable name="varD" select="4"/>
<xsl:call-template name="complexWidget">
<xsl:with-param name="a" select="$varA"/>
<xsl:with-param name="b" select="$varB"/>
<xsl:with-param name="c" select="$varC"/>
<xsl:with-param name="d" select="$varD"/>
</xsl:call-template>
</xsl:template>
<xsl:template name="complexWidget">
<xsl:param name="a"/>
<xsl:param name="b"/>
<xsl:param name="c"/>
<xsl:param name="d"/>
<!-- do something-->
<xsl:value-of select="$a"/>
<xsl:text>-</xsl:text>
<xsl:value-of select="$b"/>
<xsl:text>-</xsl:text>
<xsl:value-of select="$c"/>
<xsl:text>-</xsl:text>
<xsl:value-of select="$d"/>
</xsl:template>
</xsl:stylesheet>
When I run the output as xslt stylesheet it produces expected output.
But I don't have any deeper experience with producing xslt stylesheet by another xslt so I don't know much about possible troubles with this approach.

XSLT 1.0 String split template not working

I am new to XSLT and am having an issue with templates. I have an input xml file as follows:
<?xml version="1.0" encoding="UTF-8"?>
<Node>
<PHASE1_TYPE>LEFT,TOP</PHASE1_TYPE>
<PHASE1_HOL>TOK,ZUR,VIN</PHASE1_HOL>
<PHASE2_TYPE>RIGHT,BOTTOM</PHASE2_TYPE>
<PHASE2_HOL>CHF</PHASE2_HOL>
</Node>
My xslt is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform" >
<xsl:template name="tokenize">
<xsl:param name="text" select="."/>
<xsl:param name="separator" select="','"/>
<xsl:choose>
<xsl:when test="not(contains($text, $separator))">
<Holiday>
<xsl:value-of select="normalize-space($text)"/>
</Holiday>
</xsl:when>
<xsl:otherwise>
<Holiday>
<xsl:value-of select="normalize-space(
substring-before($text, $separator))"/>
</Holiday>
<xsl:call-template name="tokenize">
<xsl:with-param name="text"
select="substring-after($text, $separator)"/>
</xsl:call-template>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<xsl:output method="xml" encoding="UTF-8" indent="yes"/>
<xsl:template match="/">
<Document>
<xsl:attribute name="xsi:noNamespaceSchemaLocation"
namespace="http://www.w3.org/2001/XMLSchema-instance"
>C:/usr/NONMAR~1/Output.xsd</xsl:attribute>
<xsl:for-each select="Node">
<Deal>
<DealType>
<xsl:value-of select="string(PHASE1_TYPE)"/>
</DealType>
<Holidays>
<xsl:call-template name="tokenize">
<xsl:with-param name="text" select="string(PHASE1_HOL)"/>
<xsl:with-param name="separator" select="','"/>
</xsl:call-template>
</Holidays>
</Deal>
<Deal>
<DealType>
<xsl:value-of select="string(PHASE2_TYPE)"/>
</DealType>
<Holidays>
<xsl:call-template name="tokenize">
<xsl:with-param name="text" select="string(PHASE2_HOL)"/>
<xsl:with-param name="separator" select="','"/>
</xsl:call-template>
</Holidays>
</Deal>
</xsl:for-each>
</Document>
</xsl:template>
</xsl:stylesheet>
After transformation, my output is:
<?xml version="1.0" encoding="UTF-8"?>
<Document xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="C:/usr/NONMAR~1/Output.xsd">
<Deal>
<DealType>LEFT,TOP</DealType>
<Holidays>
<Holiday/>
</Holidays>
</Deal>
<Deal>
<DealType>RIGHT,BOTTOM</DealType>
<Holidays>
<Holiday/>
</Holidays>
</Deal>
</Document>
but the expected Output is :
<?xml version="1.0" encoding="UTF-8"?>
<Document xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="C:/usr/NONMAR~1/Output.xsd">
<Deal>
<DealType>LEFT,TOP</DealType>
<Holidays>
<Holiday>TOK</Holiday>
<Holiday>ZUR</Holiday>
<Holiday>VIN</Holiday>
</Holidays>
</Deal>
<Deal>
<DealType>RIGHT,BOTTOM</DealType>
<Holidays>
<Holiday>CHF</Holiday>
</Holidays>
</Deal>
</Document>
I am using xslt 1.0 and do not want to use third party functions like EXSLT. Again, I am new to XSLT and do not have time right now to learn it. Would really appreciate if someone can tell me why this template is not working properly. Thanks!!

Sorry, but it's impossible to tell, from the information you provide.
On the plus side, you've taken some effort to cut your stylesheet and your sample input down in size and simplify them. That's good; I wish more new Stack Overflow users knew to do that.
On the minus side, the code you provide doesn't produce the output you show from the input you show. First of all, it's not well-formed; the end-tag for an xsl:for-each has gotten left out. And then that for-each, in the template for the document node, uses select="Node", which looks for elements named Node which are children of the document node -- but in your input, the only element child of the document node is named 'Root'. And your tokenization template wraps the individual tokens in item elements, instead of Holiday elements. When the first two slips are fixed, the stylesheet appears to produce the output you desire (modulo the Holiday/item issue):
<?xml version="1.0" encoding="UTF-8"?>
<Document xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation=
"C:/usr/NONMAR~1/Output.xsd">
<Deal>
<DealType>LEFT,TOP</DealType>
<Holidays>
<item>TOK</item>
<item>ZUR</item>
<item>VIN</item>
</Holidays>
</Deal>
<Deal>
<DealType>RIGHT,BOTTOM</DealType>
<Holidays>
<item>CHF</item>
</Holidays>
</Deal>

XSLT get Node by Index

i am beginner in XSLT and i am using it to transform XML to XML
This is the source XML i receive
Source XML:
<Response>
<Pax>
<Id>1</Id>
</Pax>
<Pax>
<Id>2</Id>
</Pax>
<Travelers>
<Traveler>
<Name>ABC</Name>
</Traveler>
<Traveler>
<Name>XYZ</Name>
</Traveler>
</Travelers>
</Response>
I have written below XSLT
XSLT:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output method="xml" indent="yes" />
<xsl:template match="Response">
<xsl:element name="Root">
<xsl:apply-templates select="Travelers/Traveler"/>
</xsl:element>
</xsl:template>
<xsl:template match="Traveler">
<xsl:element name="Person">
<xsl:element name="PId">
<xsl:value-of select="//Pax/Id[position()]" />
</xsl:element>
<xsl:element name="Name">
<xsl:value-of select="Name" />

</xsl:element>
</xsl:template>
</xsl:stylesheet>
Output:
<Root>
<Person>
<PId>1</PId>
<Name>ABC</Name>
</Person>
<Person>
<PId>1</PId>
<Name>XYZ</Name>
</Person>
</Root>
I would like to generate below XML output
Expected Output:
<Root>
<Person>
<PId>1</PId>
<Name>ABC</Name>
</Person>
<Person>
<PId>2</PId>
<Name>XYZ</Name>
</Person>
</Root>
As shown in above XML the only issue is with PId, it should have value 2.
Please help. Thanks.

Here's a relatively simple solution.
When this XSLT:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output omit-xml-declaration="yes" indent="yes" />
<xsl:strip-space elements="*" />
<xsl:template match="/*">
<Root>
<xsl:apply-templates select="Pax" />
</Root>
</xsl:template>
<xsl:template match="Pax">
<xsl:variable name="vPosition" select="position()" />
<Person>
<PId>
<xsl:value-of select="Id" />
</PId>
<Name>
<xsl:value-of select="/*/Travelers/*[$vPosition]/Name" />
</Name>
</Person>
</xsl:template>
</xsl:stylesheet>
...is applied to the original XML:
<Response>
<Pax>
<Id>1</Id>
</Pax>
<Pax>
<Id>2</Id>
</Pax>
<Travelers>
<Traveler>
<Name>ABC</Name>
</Traveler>
<Traveler>
<Name>XYZ</Name>
</Traveler>
</Travelers>
</Response>
...the wanted result is produced:
<Root>
<Person>
<PId>1</PId>
<Name>ABC</Name>
</Person>
<Person>
<PId>2</PId>
<Name>XYZ</Name>

XSL 1.0 - Hiding Child nodes when child element is Null

I have been trying to make child elements of my structure hide based upon them being empty.
From reading other posts I found this Remove parent node if a child node is empty but I don't understand it enough to implement it in my XSL. I have had a try at applying the linked post to my XSL but it does not make the desired changes to my output.
So my XML is like this:
<?xml version="1.0" encoding="UTF-8" ?>

And my XSL looks like the passaage below. I have a nil element template that I added in as I thought looking for a value was easier than looking for a nulll so happy for it to come out if not needed.
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xd="http://www.oxygenxml.com/ns/doc/xsl" exclude-result-prefixes="xd" version="1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="/exchange/sce">
<ImportTask>
<EntityRelationshipEntities>
<xsl:apply-templates select="node()|#*"/>
</EntityRelationshipEntities>
</ImportTask>
</xsl:template>
<xsl:template name="nilElement">
<xsl:param name="value"/>
<xsl:choose>
<xsl:when test="string($value)">
<xsl:value-of select="$value"/>
</xsl:when>
<xsl:otherwise>
<xsl:attribute name="xsi:nil" namespace="http://www.w3.org/2001/XMLSchema-instance">True</xsl:attribute>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<xsl:template match="sce.srs[not(*/AttributeValue[not(#AttributeValue='True')])]">
<xsl:for-each select="spr/spr.cams">
<EntityRelationshipEntity>
<ErRef>ERREF_21</ErRef>
<EntityCode><xsl:value-of select="../../sce_stuc.sce.srs"/></EntityCode>
<AttributeValue>
<xsl:call-template name="nilElement">
<xsl:with-param name="value" select="prs/prs.mensys/prs_name.prs.mensys"/>
</xsl:call-template>
</AttributeValue>
<Action>VALUEONLY</Action>
</EntityRelationshipEntity>
</xsl:for-each>
</xsl:template>
<xsl:template match="AttributeValue[#AttributeValue = 'True']"/>
</xsl:stylesheet>
So this currently gives me:
<ImportTask xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<EntityRelationshipEntities>
<EntityRelationshipEntity>
<ErRef>ERREF_21</ErRef>
<EntityCode>151514490</EntityCode>
<AttributeValue xsi:nil="True"/>
<Action>VALUEONLY</Action>
</EntityRelationshipEntity>
<EntityRelationshipEntity>
<ErRef>ERREF_21</ErRef>
<EntityCode>140008305</EntityCode>
<AttributeValue>Johan</AttributeValue>
<Action>VALUEONLY</Action>
</EntityRelationshipEntity>
<EntityRelationshipEntity>
<EntityCode>151516736</EntityCode>
<AttributeValue>Evangelia</AttributeValue>
<Action>VALUEONLY</Action>
</EntityRelationshipEntity>
</EntityRelationshipEntities>
</ImportTask>
What I would like to produce is out those where is not null. This would mean that the child below is not output:
<EntityRelationshipEntity>
<ErRef>ERREF_21</ErRef>
<EntityCode>151514490</EntityCode>
<AttributeValue xsi:nil="True"/>
<Action>VALUEONLY</Action>
</EntityRelationshipEntity>
But the others would be output something like this:
<ImportTask xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<EntityRelationshipEntities>
<EntityRelationshipEntity>
<ErRef>ERREF_21</ErRef>
<EntityCode>140008305</EntityCode>
<AttributeValue>Johan</AttributeValue>
<Action>VALUEONLY</Action>
</EntityRelationshipEntity>
<EntityRelationshipEntity>
<EntityCode>151516736</EntityCode>
<AttributeValue>Evangelia</AttributeValue>
<Action>VALUEONLY</Action>
</EntityRelationshipEntity>
</EntityRelationshipEntities>
</ImportTask>
Can someone help me apply this correctly?
Many thanks
Jonah

Perhaps I am missing something, but couldn't this be simply:
