Ever wondered when we print xml, instead of printing it in single line can’t we print with proper formatting and indentation.  If you are using Jaxb then there is a  nice little trick in  to achieve that.

JAXBContext jc = JAXBContext.newInstance( "MyClass.class" );

Marshaller marshaller = jc.createMarshaller();

marshaller.setProperty( Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE );

marshaller.marshal( <object_to_marshal>, System.out );
