Как запустить мою программу реакции на моем устройстве IOS

Попробуйте следующее:

 try
                    {
                        TransformerFactory transFactory = TransformerFactory.newInstance();
                        Transformer transformer = null;
                        transformer = transFactory.newTransformer();
                        StringWriter buffer = new StringWriter();
                        transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
                        transformer.transform(new DOMSource(element),
                                  new StreamResult(buffer)); 
                        String str = buffer.toString();
                        System.out.println("XML INSIDE IS #########################################"+str);
                        return element;
                    }
                    catch (TransformerConfigurationException e)
                    {
                        e.printStackTrace();
                    }
                    catch (TransformerException e)
                    {
                        e.printStackTrace();
                    }
