I wrote a JSON parser and am open sourcing it. Feel free to use it in your channels and let me know how it works for you.
You can find it at
http://bitbucket.org/chrishoffman/brightscript-json/I have not benchmarked this against the built in XML parser. This is written in BrightScript where the XML parser is probably better integrated in the framework. If your API offers both types of feeds, keep this in mind when you are making your decision.
Known Issues
- Unicode escaped characters are skipped since BrightScript does not support them
If you find any bugs or run into issues, add a bug to the issues tracker or fork it and let me know the changeset of the fix.
