Error in mapping or source ?

Question

Hello Experts,
I hope you can help me with following issue ...
I trying to set-up an file to idoc scenario using file content conversion but I have an issue in my mapping and I know what is missing but don't know how to fix it...
My source xml is missing ns0:
I have this
<?xml version="1.0" encoding="utf-8" ?>
<MT_ACC_DOCUMENT>
<Recordset>
<DOCUMENT>
instead of this
<?xml version="1.0" encoding="utf-8" ?>
<ns0:MT_ACC_DOCUMENT xmlns:ns0="http://connectsystems.be/MAINFR/AccDocument">
<Recordset>
<DOCUMENT>
Can somebody please help me or advice me how to solve this??
Thank you very much.
Best regards,

Hi Daisy Heremans,
  You could use a java mapping code as shown below.
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.Map;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
import com.sap.aii.mapping.api.StreamTransformation;
import com.sap.aii.mapping.api.StreamTransformationException;
public class DOMParser3 implements StreamTransformation{
public void execute(InputStream in, OutputStream out)
throws StreamTransformationException {
try
     DocumentBuilderFactory factory=DocumentBuilderFactory.newInstance();
     DocumentBuilder builderel=factory.newDocumentBuilder();
     /*input document in form of XML*/
     Document docIn=builderel.parse(in);
     /*document after parsing*/
     Document docOut=builderel.newDocument();
     TransformerFactory tf=TransformerFactory.newInstance();
     Transformer transform=tf.newTransformer();
     Element root;
     Node p;
     NodeList l;
     int mm,n1;
     root=docOut.createElement("ns0:MT_ACC_DOCUMENT");
     root.setAttribute("xmlns:ns0","http://connectsystems.be/MAINFR/AccDocument");
     p=docIn.getElementsByTagName("MT_ACC_DOCUMENT").item(0);
     System.out.println(p.getNodeName());
     l=p.getChildNodes();
     n1=l.getLength();
     System.out.println(n1);
     for(mm=0;mm<n1;++mm)
          Node temp=docOut.importNode(l.item(mm),true);
          root.appendChild(temp);
     docOut.appendChild(root);
     transform.transform(new DOMSource(docOut), new StreamResult(out));
catch(Exception e)
     e.printStackTrace();
public void setParameter(Map arg0) {
public static void main(String[] args) {
try{
     DOMParser3 genFormat=new DOMParser3();
     FileInputStream in=new FileInputStream("C:\\Apps\\my folder\\sdn\\input1.xml");
     FileOutputStream out=new FileOutputStream("C:\\Apps\\my folder\\sdn\\output1.xml");
     genFormat.execute(in,out);
catch(Exception e)
e.printStackTrace();
sample input1.xml as seen is internet explorer
  <?xml version="1.0" encoding="utf-8" ?>
- <MT_ACC_DOCUMENT>
- <Recordset>
  <DOCUMENT>mydocument</DOCUMENT>
  </Recordset>
  </MT_ACC_DOCUMENT>
Output1.xml as seen in browser
  <?xml version="1.0" encoding="UTF-8" ?>
- <ns0:MT_ACC_DOCUMENT xmlns:ns0="http://connectsystems.be/MAINFR/AccDocument">
- <Recordset>
  <DOCUMENT>mydocument</DOCUMENT>
  </Recordset>
  </ns0:MT_ACC_DOCUMENT>
If you are new to java mapping you can follow the links shown below
