# flash-ext-jackson-xml

XML bodies and XML responses, over the same types as every other Jackson format.

```java
XmlExtension xml = new XmlExtension();
app.install(xml).use(xml.auto());
```

```java
@POST("/orders")
public final class PlaceOrder extends XmlHandler<Order> {
    @Inject private OrderService orders;

    @Override protected Object handle(Request req, Response res, Order body) {
        return orders.place(body);
    }
}
```

Everything [`flash-ext-jackson-json`](../flash-ext-jackson-json) does, in XML: the body is read off
the request stream, verified against the constraints its type declares, and handed over. A type
annotated for JSON works here as is — `Order` can be a JSON body on one route and an XML body on
another.

What is specific to XML is Jackson's own: `@JacksonXmlRootElement` for the root name,
`@JacksonXmlProperty(isAttribute = true)` for an attribute rather than an element, and
`@JacksonXmlElementWrapper` for how a list is wrapped. This module adds no annotations of its own.

Brings `jackson-dataformat-xml`, and with it Woodstox.
