Usage

From source file:Main.java

public static void main(String[] args) throws Exception {
    JAXBContext jc = JAXBContext.newInstance(Root.class);
    Unmarshaller unmarshaller = jc.createUnmarshaller();
    File xml = new File("input.xml");
    Root root = (Root) unmarshaller.unmarshal(xml);

    Marshaller marshaller = jc.createMarshaller();
    marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
