Re: how to convert xml file to a string and write that string to another XML file format in XI/PI?

public void transform(TransformationInput transformationInput, TransformationOutput transformationOutput) throws StreamTransformationException { 

         try { 

             InputStream inputstream = transformationInput.getInputPayload().getInputStream(); 

             OutputStream outputstream = transformationOutput.getOutputPayload().getOutputStream(); 

             // a) Copy Input content to String 

             byte[] b = new byte[inputstream.available()]; 

             inputstream.read(b); 

             String inputContent = new String(b); 

             inputContent = inputContent.replaceAll("<?xml version= \"1.0\" encoding= \"UTF-8\" ?>", ""); 

             outputstream.write(inputContent.getBytes()); 

         } catch (Exception exception) { 

             getTrace().addDebugMessage(exception.getMessage()); 

             throw new StreamTransformationException(exception.toString()); 

         } 

     }
