XML Extract mapping using xsd with 0 to 5 elements

Using xml/xsd below, I want a mapped single record.
45252|Document1| Document2| Document3| Document4|Document5
Note, Document can have 0 to 5 occurrences per record.

How do I do this with XML Extract. Presently, it just grabs the last occurence of Document. For example, 45252|Document5.

<xs:schema xmlns:xs=“http://www.w3.org/2001/XMLSchema”>
<xs:element name=“XCars”>
xs:complexType
xs:sequence
<xs:element ref=“Car” maxOccurs=“unbounded” />
</xs:sequence>
</xs:complexType>
</xs:element>

<xs:element name=“Car”>
xs:complexType
xs:sequence
<xs:element ref=“SerialNumber” />
<xs:element ref=“Document” minOccurs=“0” />
</xs:sequence>
</xs:complexType>
</xs:element>

<xs:element name=“DocumentNumber” type=“xs:string” />
<xs:element name=“SerialNumber” type=“xs:string” />

12345 Document1 Document2 Document3 Document4 Document5 /

Hello,
it is impossible to do it in one step. But you can read the file with following mapping:

<Mappings>
	<Mapping element="XCars">
		<Mapping element="Car">
			<Mapping element="Document" outPort="0"
					xmlFields="DocumentNumber;../SerialNumber"
					cloverFields="Document;SerialNumber"/>
		</Mapping>
	</Mapping>
</Mappings>

and then join all records with the same SerialNumber with the Denormalizer component.
