Formats (This is DEPRECATED functionality! Please have a look at Transformation Schemas instead)

Since version 1.2.0 of Datafaker it's possible to export generated data to a file format of your choice.

The currently supported file formats are:

  • XML

XML

Elements and attributes

In case you want to generate XML, Datafaker provides a facility to build XML elements and attributes using randomly generated data in the following way: 

public static void main(String[] args) {
    Faker faker = new Faker();

    Collection<Xml.XmlNode> address = faker.<Xml.XmlNode>collection()
            .suppliers(() -> new Xml.XmlNode("address",
                    map(entry("country", faker.address().country()),
                            entry("city", faker.address().city()), entry("streetAddress", faker.address().streetAddress())), Collections.emptyList()))
            .maxLen(3).build().get();

    Collection<Xml.XmlNode> persons = faker.<Xml.XmlNode>collection()
            .suppliers(() -> new Xml.XmlNode("person",
                    map(entry("firstname", faker.name().firstName()),
                            entry("lastname", faker.name().lastName())),
                    of(new Xml.XmlNode("addresses", address)))).maxLen(3).build().get();

    String str = new Xml(new Xml.XmlNode("persons", persons)).generate(true);
    System.out.println(str);
}

private static <T> Collection<T> of(T... elems) {
    return Arrays.asList(elems);
}

private static Map.Entry<String, String> entry(String key, String value) {
    return new AbstractMap.SimpleEntry<>(key, value);
}

private static Map<String, String> map(Map.Entry<String, String>... entries) {
    Map<String, String> map = new LinkedHashMap<>();
    for (Map.Entry<String, String> entry : entries) {
        map.put(entry.getKey(), entry.getValue());
    }
    return map;
}

This will produce the following output:

<persons>
    <person firstname="Chuck" lastname="Rice">
        <addresses>
            <address country="Croatia" city="South Stacimouth" streetAddress="8958 Ervin Stravenue"/>
            <address country="Uruguay" city="South Cariefort" streetAddress="59014 Howell Pike"/>
            <address country="Bahrain" city="New Ian" streetAddress="446 Wuckert Brooks"/>
        </addresses>
    </person>
    <person firstname="Brent" lastname="Walter">
        <addresses>
            <address country="Croatia" city="South Stacimouth" streetAddress="8958 Ervin Stravenue"/>
            <address country="Uruguay" city="South Cariefort" streetAddress="59014 Howell Pike"/>
            <address country="Bahrain" city="New Ian" streetAddress="446 Wuckert Brooks"/>
        </addresses>
    </person>
    <person firstname="Amy" lastname="Parisian">
        <addresses>
            <address country="Croatia" city="South Stacimouth" streetAddress="8958 Ervin Stravenue"/>
            <address country="Uruguay" city="South Cariefort" streetAddress="59014 Howell Pike"/>
            <address country="Bahrain" city="New Ian" streetAddress="446 Wuckert Brooks"/>
        </addresses>
    </person>
</persons>

Elements only

In case you only want to generate XML elements, without any attributes, that possible too:

Faker faker = new Faker();
Collection<Xml.XmlNode> address = faker.<Xml.XmlNode>collection()
        .suppliers(() -> new Xml.XmlNode("address",
                of(new Xml.XmlNode("country", faker.address().country()),
                        new Xml.XmlNode("city", faker.address().city()),
                        new Xml.XmlNode("streetAddress", faker.address().streetAddress()))))
        .maxLen(4).build().get();
Collection<Xml.XmlNode> persons = faker.<Xml.XmlNode>collection()
        .suppliers(() -> new Xml.XmlNode("person",
                of(new Xml.XmlNode("firstname", faker.name().firstName()),
                        new Xml.XmlNode("lastname", faker.name().lastName()),
                        new Xml.XmlNode("addresses", address)))).maxLen(2).build().get();

String str = new Xml(new Xml.XmlNode("persons", persons)).generate(true);
System.out.println(str);

Executing the above will result in:

<persons>
    <person>
        <firstname>Shiloh</firstname>
        <lastname>Witting</lastname>
        <addresses>
            <address>
