Issue while devpl flowservice as schemabased Pip3A4?

Hi,
i am developing the flow service which has input as XMLstring & output as Rosettanet Pip 3A4document(schema base structure PIP 3A4).
basically i want to convert xmlstring value into schema based Pip3A4 document as output of the flow service.
schema based Pip3A4 structure ==contains nodes & namespaces
flow service coded as follows

1 Input as XmlSting pub.xml.xmlStringToxmlNode(map xmlstring to node)
2 pub.xml.xmlNodeToDocument(xmlnode to Pip3A4document)
3 Map step(extracting value from Pip3A4document into temp field).

here issue is while extracting value from Pip3A4 document in step 3 & i am not able to get any value in temp field.

as per documentation guide
In step 2 built in service pub.xml.xmlNodeToDocument in Piplinevalue i have set the Service in value to:-
a makeArray=flase
b nsDecls==all nodes & namespaces contain in pip3A4 ( as i told you before it a schema base pip)
documentTypeName==name of document

Find the attached screeshot of schemabased Pip 3A4structure.
& sample xml file with raw data which basicaly use to feed at start of service as XMLString inputs.

here issue is while extracting value from Pip3A4 document in step 3 & i am not able to get any value in temp field.

Apprecitate you reply

Thnx
