XML output File Format change

Question

Hi experts,
I am currenty getting below output in my XML file and it is wrapped in message type MT_Test.
<?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_Test xmlns:ns0="http://test.com/xi/T1/Data">
<Tests>
<schemaLocation>http://tempuri.org/TestSchema.xsd F:/documentation/MID/Release-Test/TestSchema.xsd</schemaLocation>
<Test>
<HeaderID>This is a string 1</HeaderID>
</Test>
</Tests>
</ns0:MT_Test>
and I want to change it to the below format.
<?xml version="1.0" ?>
<Tests xmlns="http://tempuri.org/TestSchema.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://tempuri.org/TestSchema.xsd F:/documentation/TEMP/Release-Test/TestSchema.xsd">
<Test HeaderID="RES-996-25885-527">
</Test>
</Tests>
Request you to give your inputs on how I can achieve this?

Hi ,
         You need a java mapping to produce exactly the output you posted here.
I assume you r working with PI 7.1 here is the java mapping code.
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 org.w3c.dom.Document;
import org.w3c.dom.NodeList;
import com.sap.aii.mapping.api.AbstractTransformation;
import com.sap.aii.mapping.api.StreamTransformationException;
import com.sap.aii.mapping.api.TransformationInput;
import com.sap.aii.mapping.api.TransformationOutput;
public class FormatXML extends AbstractTransformation{
     public void execute(InputStream in, OutputStream out)
     throws StreamTransformationException {
          try{
          // TODO Auto-generated method stub
          DocumentBuilderFactory factory=DocumentBuilderFactory.newInstance();
          DocumentBuilder builderel=factory.newDocumentBuilder();
          /*input document in form of XML*/
          Document docIn=builderel.parse(in);
          NodeList l=null;
          String schemaLocation="";
          l=docIn.getElementsByTagName("schemaLocation");
          if(l!=null)
               schemaLocation=l.item(0).getTextContent();
               schemaLocation=schemaLocation.replaceFirst("/MID/", "/TEMP/");
          String outPut="<?xml version=\"1.0\" ?><Tests xmlns=\"http://tempuri.org/TestSchema.xsd\" " +
                              "xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" " +
                              "xsi:schemaLocation=\""+schemaLocation+"\">"
                              +"<Test HeaderID=\"RES-996-25885-527\">"
                              +"</Test></Tests>";
          out.write(outPut.getBytes("UTF-8"));
          catch(Exception e)
               throw new StreamTransformationException(e.getCause().toString());
     public void setParameter(Map arg0) {
          // TODO Auto-generated method stub
     public static void main(String[] args) {
          // TODO Auto-generated method stub
          try{
               FormatXML genFormat=new FormatXML();
               FileInputStream in=new FileInputStream("C:\\Apps\\sdn\\format.xml");
               FileOutputStream out=new FileOutputStream("C:\\Apps\\sdn\\format1.xml");
               genFormat.execute(in,out);
               catch(Exception e)
               e.printStackTrace();
     public void transform(TransformationInput arg0, TransformationOutput arg1)
               throws StreamTransformationException {
      this.execute(arg0.getInputPayload().getInputStream(), arg1.getOutputPayload().getOutputStream());
If you are new to java mapping pls follow this  http://www.****************/Tutorials/XI/Mapping/Index.htm
You need to install eclipse and java 1.5.0 for PI 7.1. You also need proper library files for PI 7.1 which you need to download from PI server. Please follow this link http://wiki.sdn.sap.com/wiki/display/XI/WheretogetthelibrariesforXI+development
