Array in WSDL

Question

Hi there,
I have a Proxy->PI->SOAP scenario.
The third-party WSDL contains an array, which is unfortunately not supported by PI.
The complex type looks as following:
<xs:complexType name="EmployeeInfo">
  <xs:sequence>
  <xs:element name="ID" type="xs:string"/>
  <xs:element name="Name" type="xs:string"/>
  <xs:element name="Qual" type="ns1:QualItems"/>
</xs:sequence>
</xs:complexType>
This is the array structure:
<xs:complexType name="QualItems">
  <xs:complexContent>
  <xs:restriction base="soapenc:Array">
  <xs:sequence/>
  <xs:attribute xmlns:n1="http://schemas.xmlsoap.org/wsdl/"
ref="soapenc:arrayType" n1:arrayType="ns1:QualRec[]"/>
  </xs:restriction>
  </xs:complexContent>
</xs:complexType>
<xs:complexType name="QualRec">
  <xs:sequence>
  <xs:element name="QualPos" type="xs:string"/>
  </xs:sequence>
</xs:complexType>
Ive tried to change the WSDL in the following way:
<xs:complexType name="EmployeeInfo">
  <xs:sequence>
  <xs:element name="ID" type="xs:string"/>
  <xs:element name="Name" type="xs:string"/>
  <xs:element name="Qual" type="QualRec" minOccurs="1" maxOccurs="unbound"/>
  </xs:sequence>
</xs:complexType>
But the field "QualPos" is not filled in the thir-party application.
I now asked the service provider to send me a proper payload for the web service.
It looks like that:
<Qual href="#id2" />
<soapenc:Array id="id2" xmlns:q4="urn:XXX" soapenc:arrayType="q4:TSAPQualRec[1]">
  <Item href="#id3" />
</soapenc:Array>
<q5:QualRec id="id3" xsi:type="q5:TSAPQualRec" xmlns:q5="urn:XXX">
  <QualPos xsi:type="xsd:string">XYZ</QualPos>
</q5:QualRec>
How can I achieve that in PI?
Do I have to use XSLT mapping?
Could you please give me an example?
Thanks in advance!

Hi Kolz,
A few cents. This can be done by PI, you can use a XSL or Java Mapping. Personally, i'd rather to use XSL mapping.
If you need to do the array in the request you would need only to set the tag soapen:Array manually in the XSL (if its the attributes are not parameters) and the rest with a value-of-select.
If you need to transform a response with the array you only need to do a for:each like this example looping through xslt split array - Xslt - our.umbraco.org
Finally, if you share a source XML and target XML (hidding the company information with another values) we can help you with the XSL easier.
Hope this helps.
Regards.
