How do you map a abstract XSD element in Xquery? - xsd

Question

I have a form that I am defining in my Xquery request. This form is built on an XSD schema.
My form:
<xsd:element name="AddInsuranceToOrderForm">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="OrderId" type="xsd:long" minOccurs="1" maxOccurs="1"/>
<xsd:element name="DistributionChannel" type="xsd:long" minOccurs="1" maxOccurs="1"/>
<xsd:element name="FloatNumber" type="xsd:long" minOccurs="1" maxOccurs="1"/>
<xsd:element name="UserId" type="xsd:long" minOccurs="1" maxOccurs="1"/>
<xsd:element name="SalesId" type="xsd:long" minOccurs="1" maxOccurs="1"/>
<xsd:element name="TotalDue" type="xsd:decimal" minOccurs="1" maxOccurs="1"/>
<xsd:element name="ChangeDue" type="xsd:decimal" minOccurs="1" maxOccurs="1"/>
**<xsd:element ref="tns:tenderItem" minOccurs="0" maxOccurs="unbounded"/>**
<xsd:element name="ProtectionPlans" type="tns:ProtectionPlanItemType" minOccurs="0" maxOccurs="unbounded"/>
<xsd:element name="InsurancePlans" type="tns:FeatureItemType" minOccurs="0" maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
Notice tenderItems is a ref. It's source is here:
<xsd:element abstract="true" name="tenderItem" type="tns:TenderType"/>
<xsd:complexType name="TenderType">
<xsd:sequence>
<xsd:element maxOccurs="1" minOccurs="0" name="date" type="xsd:dateTime"/>
<xsd:element maxOccurs="1" minOccurs="0" name="lineNumber" type="xsd:string"/>
<xsd:element maxOccurs="1" minOccurs="0" name="tenderId" type="xsd:long"/>
<xsd:element maxOccurs="1" minOccurs="0" name="returnTenderId" type="xsd:long"/>
<xsd:element maxOccurs="1" minOccurs="0" name="tenderType" type="tns:TenderTypeType"/>
<xsd:element maxOccurs="1" minOccurs="0" name="amount" type="xsd:decimal"/>
<xsd:element maxOccurs="1" minOccurs="0" name="signature" type="tns:SignatureType"/>
</xsd:sequence>
</xsd:complexType>
There are several specific tenders that extend tenderType that I want to add to my Xquery request. Here is an example:
<xsd:element name="billToAccount" substitutionGroup="tns:tenderItem" type="tns:BillToAccountType"/>
<xsd:complexType name="BillToAccountType">
<xsd:complexContent>
<xsd:extension base="tns:TenderType">
<xsd:sequence>
<xsd:element maxOccurs="1" minOccurs="0" name="accountId" type="xsd:long"/>
<xsd:element maxOccurs="1" minOccurs="0" name="subscriptionId" type="xsd:string"/>
<xsd:element maxOccurs="1" minOccurs="0" name="chargeDescription" type="xsd:string"/>
<xsd:element maxOccurs="unbounded" minOccurs="0" name="lineItems" type="tns:BillToAccountLineItemType"/>
</xsd:sequence>
</xsd:extension>
</xsd:complexContent>
</xsd:complexType>
So how is this done in Xquery? I've tried the following:
{
for $BillToAccount in $addInsuranceToOrderABM1/ns3:MessagePayload/ns3:AddInsuranceToOrder/ns1:AddInsuranceToOrderDataArea/ns2:TenderItem
return
<ns2:billToAccount>
{
for $Date in $BillToAccount/ns0:Date
return
<ns2:date>{ data($Date) }</ns2:date>
}…
}
I did this for each tenderType, but the XML elements are not supported by the mapper.

You can use schema-element(ns3:tenderItem) to match any element in that substitution-group.
import schema default element namespace "http://www.example.com/xml-namespace/" at "schema.xsd";
declare variable $input as schema-element(AddInsuranceToOrderForm)
:= validate { doc('data.xml')/AddInsuranceToOrderForm };
for $item in $input/schema-element(tenderItem)
return $item
With schema.xsd as:
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified"
xmlns:tns="http://www.example.com/xml-namespace/"
targetNamespace="http://www.example.com/xml-namespace/">
<xsd:element name="AddInsuranceToOrderForm">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="OrderId" type="xsd:long" minOccurs="1" maxOccurs="1"/>
<xsd:element name="DistributionChannel" type="xsd:long" minOccurs="1" maxOccurs="1"/>
<xsd:element name="FloatNumber" type="xsd:long" minOccurs="1" maxOccurs="1"/>
<xsd:element name="UserId" type="xsd:long" minOccurs="1" maxOccurs="1"/>
<xsd:element name="SalesId" type="xsd:long" minOccurs="1" maxOccurs="1"/>
<xsd:element name="TotalDue" type="xsd:decimal" minOccurs="1" maxOccurs="1"/>
<xsd:element name="ChangeDue" type="xsd:decimal" minOccurs="1" maxOccurs="1"/>
<xsd:element ref="tns:tenderItem" minOccurs="0" maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
<xsd:element abstract="true" name="tenderItem" type="tns:TenderType"/>
<xsd:complexType name="TenderType">
<xsd:sequence>
<xsd:element maxOccurs="1" minOccurs="0" name="date" type="xsd:dateTime"/>
<xsd:element maxOccurs="1" minOccurs="0" name="lineNumber" type="xsd:string"/>
<xsd:element maxOccurs="1" minOccurs="0" name="tenderId" type="xsd:long"/>
<xsd:element maxOccurs="1" minOccurs="0" name="returnTenderId" type="xsd:long"/>
<xsd:element maxOccurs="1" minOccurs="0" name="amount" type="xsd:decimal"/>
</xsd:sequence>
</xsd:complexType>
<xsd:element name="BillToAccount" substitutionGroup="tns:tenderItem" type="tns:BillToAccountType"/>
<xsd:complexType name="BillToAccountType">
<xsd:complexContent>
<xsd:extension base="tns:TenderType">
<xsd:sequence>
<xsd:element maxOccurs="1" minOccurs="0" name="accountId" type="xsd:long"/>
<xsd:element maxOccurs="1" minOccurs="0" name="subscriptionId" type="xsd:string"/>
<xsd:element maxOccurs="1" minOccurs="0" name="chargeDescription" type="xsd:string"/>
</xsd:sequence>
</xsd:extension>
</xsd:complexContent>
</xsd:complexType>
</xsd:schema>
And data.xml as:
<?xml version="1.0" encoding="UTF-8"?>
<AddInsuranceToOrderForm xmlns="http://www.example.com/xml-namespace/">
<OrderId>1</OrderId>
<DistributionChannel>1</DistributionChannel>
<FloatNumber>1</FloatNumber>
<UserId>1</UserId>
<SalesId>1</SalesId>
<TotalDue>1</TotalDue>
<ChangeDue>1</ChangeDue>
<BillToAccount>
<date>2012-10-01T23:59:59</date>
<lineNumber>line 1</lineNumber>
<tenderId>1</tenderId>
<returnTenderId>1</returnTenderId>
<amount>1.2</amount>
<accountId>1</accountId>
<subscriptionId>1</subscriptionId>
<chargeDescription>1</chargeDescription>
</BillToAccount>
</AddInsuranceToOrderForm>
Gives output:
<?xml version="1.0" encoding="UTF-8"?>
<BillToAccount xmlns="http://www.example.com/xml-namespace/">
<date>2012-10-01T23:59:59</date>
<lineNumber>line 1</lineNumber>
<tenderId>1</tenderId>
<returnTenderId>1</returnTenderId>
<amount>1.2</amount>
<accountId>1</accountId>
<subscriptionId>1</subscriptionId>
<chargeDescription>1</chargeDescription>
</BillToAccount>
