Help on JSON and Rebol
@Nick: Using this json to rebol converter (http://www.ross-gill.com/page/JSON_and_REBOL), can you do an example on how to parse values returned from this json string (http://api.jamendo.com/get2/id+name+url+image+artist_name/album/jsonpretty/?n=50&order=ratingweek_desc) ? thanks!

Rebol 2: do http://reb4.me/r/altjson result: load-json http://api.jamendo.com/get2/id+name+url+image+artist_name/album/jsonpretty/?n=50&order=ratingweek_desc foreach item result [print item/name] Rebol 3 is similar: do http://reb4.me/r3/altjson result: load-json to string! read http://..... (the 'to string! read' part is a workaround for a bug in the current version of R3 AltJson) You can DO AltJson in place--convenient for prototyping--though I'd recommend downloading it and containing it in your project folder and DOing it locally: write %altjson.r read http://reb4.me/r/altjson Then: do %altjson.r

@Chris: If I do "probe type? result" on this other one: result: load-json http://www.rai.tv/dl/portale/html/palinsesti/replaytv/static/RaiUno_2014_05_28.html it says that it's of type "object"; how can I parse it ?

load-json converts a json string to an object, you can't parse an object. If you need to parse a json string then you need to parse without loading it. Check the source of load-json function it parses json strings to build objects.

If you need to parse the results, you can use LOAD-JSON/FLAT. This refinement replaces objects with TAG-VALUE paired blocks.
