XML Support

Akka HTTP’s marshalling and unmarshalling infrastructure makes it rather easy to seamlessly support specific wire representations of your data objects, like JSON, XML or even binary encodings.

For XML Akka HTTP currently provides support for Scala XML right out of the box through it’s akka-http-xml module.

Scala XML Support

The ScalaXmlSupport trait provides a FromEntityUnmarshaller[NodeSeq] and ToEntityMarshaller[NodeSeq] that you can use directly or build upon.

This is how you enable support for (un)marshalling from and to XML with Scala XML NodeSeq:

  1. Add a library dependency onto "com.typesafe.akka" %% "akka-http-xml" % "1.x".
  2. import akka.http.scaladsl.marshallers.xml.ScalaXmlSupport._ or mix in the akka.http.scaladsl.marshallers.xml.ScalaXmlSupport trait.

Once you have done this (un)marshalling between XML and NodeSeq instances should work nicely and transparently.
