How could i create a XML file using my java object and set the specific format for this XML file?

I have to create an XML file from java object with specific format of my XML file.

My xml should look like this.

<?xml version="1.0" encoding="UTF-8"?>
<persons>
    <person
            name="Nick"
            birthday = "09.03.1814"/>
</persons>

Or like this one.

<?xml version="1.0" encoding="UTF-8"?>
<persons>
    <person surname="Sd" name="aaa" birthday = "09.03.1814"/>
</persons>

Depends on old format of xml. How could i do this? Thanks!

I've try to use this code for creating xml

public static void createNewXml(List<Person> persons) {
    List<DtoPerson> dtoPersonList = new ArrayList<>();
    for (Person person : persons) {
        dtoPersonList.add(new DtoPerson(person));
    }
    try {
        JAXBContext jaxbContext =  JAXBContext.newInstance(DtoPerson.class);
        Marshaller marshaller = jaxbContext.createMarshaller();
        File file = new File("personx.xml");
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);

        for(DtoPerson personDto : dtoPersonList) {
            marshaller.marshal(personDto, file);
        }

    } catch (JAXBException e) {
        throw new RuntimeException(e);
    }
    System.out.println(Arrays.toString(dtoPersonList.toArray()));
}

But this code create an xml with other format

<dtoPerson>
    <birthday>09.03.1814</birthday>
    <name>aaa Sd</name>
</dtoPerson>

You need to add annotation @XmlAttribute to affected fields in DtoPerson.
