XML Class Serializer

Serialize any class to XML-type using annotations and Reflection API.

Insrtuctions

1. Mark a class with the @XMLObject annotation

By default the name equals to the name of the class

@XMLObject(name = "Person")

2. Mark fields and methods with the @XMLTag annotation that you want to become tags in the resulted XML.

By default the name equals to the name of the field/method

@XMLTag(name = "Person")

3. Mark fields and methods with the @XMLAttribute annotation that you want to become attributes of the chosen tag in the resulted XML

By default added attribute will refer to the root tag

@XMLAttribute(tag = "Child", name = "age")

4. Call the serialized method of the XMLConverter

XMLConverter.serialized(person)

Specifications and requirements

• Methods must not have any parameters
• Methods cannot return void
• Access modifiers will be ignored
• The code requires jaxen and dom4j libraries

Usage examples

Define a class:

@XMLObject
public class Person {
    @XMLTag(name = "fullname")
    private final String name;

    @XMLAttribute(tag = "fullname")
    private final String lang;

    @XMLAttribute
    private final int age;

    public Person(String name, String lang, int age, ChildPerson child) {
        this.name = name;
        this.lang = lang;
        this.age = age;
        this.child = child;
    }
    public String getName() {
        return name;
    }

    public int getAge() {
        return age;
    }
}

Serialize

public class Main {
    public static void main(String[] args) {
        Person person = new Person("Sergey", "RUS", 32, new ChildPerson());

        try {
            var serialized = XMLConverter.serialized(person);
            OutputFormat format = OutputFormat.createPrettyPrint();
            var outputStream = new FileOutputStream("output.xml");
            var writer = new XMLWriter(outputStream, format);
            writer.write(serialized);
        } catch (Exception error) {
            System.out.println(error.getMessage());
        }
    }
}

output.xml

<?xml version="1.0" encoding="UTF-8"?>

<Person age="32">
  <fullname lang="RUS">Sergey</fullname>
  <Child>
    <test>test</test>
  </Child>
