Serialise to YAML using XStream in Java

Question

Is there a YAML driver for the Java XStream package?

I'm already using XStream to serialise/deserialise both XML and JSON. I'd like to be able to do the same with YAML.

Answer 1

To parse a YAML document you can use this chain: YAML -> SnakeYAML -> Java -> Your Application (-> XStream -> XML)

Emitting YAML is simpler and there are a couple of options: 1) Your Application -> XStream with Custom Writer -> YAML 2) Your Application -> SnakeYAML -> YAML

The second option does not require any additional development.

Answer 2

You might find that helpful to get a direction: XStream - how to serialize objects to non XML formats

Answer 3

I used JYAML and it worked great. I know it doesn't directly answer your question but it works well.

Answer 4

While XStream is pretty nice for XML, JSON it produces is rather ugly, due to conversion using Badgerfish notation.

But you could consider using Jackson for all 3; since while the default package just handles JSON, there are extensions for both XML and YAML, and all work using same powerful data-binding functionality, just differ on low-level parsers and generators (for XML, Stax API is used)
