When one has the option to use XML or JSON to communicate with JS libraries, which one would be better?

[MAQ]

Hi,

I hope the question is clear, I'm a total GWT newbie. My project requires the use of some of Google's APIs. Two main solutions are provided one for XML and another for JSON (gdata-java-client and google-api-java-client).

Which one would be more suitable (easier, more compatible etc.)? Or is it a mere personal choice?

Regards,

Mo

I don't understant in what context you use "solution" word but generally json is standard for api use, with gwt overlays mechanism it easy to use in java typing model.

Sorry, I meant 2 options provided by Google APIs.

I would go with JSON. 

It's more compact than XML and seems to become more and more the defacto standard for data communication in the web.

It's likely json will be processed more quickly on the client since it can be done natively, although it does depend on your use case. And json is usually smaller.

With GWT, you'll likely use gwt-google-apis rather than the above 2 projects (which i'd bet are not GWT-compatible). I believe gwt-google-apis uses JSON, but that's a detail, as there aren't actually any existing alternative.

I did look at that project, however it does not include youtube API.

So, if I had to integrate the youtube API with my GWT app, then my best option would be the JSON path?

Actually rather wrap the JS API.

(this is what gwt-google-apis do AFAICT)
