Developer's Corner General Dev Discussions

I’ve already been able to extract xml data to put value in a virtual device. I checked on the forum with no luck, is there a way to do the same with json. when i put the url in the browser here what it print out:

{“id”:“VideoGetItem”,“jsonrpc”:“2.0”,“result”:{“item”:{“id”:1,“label”:“22. Tis Pity”,“title”:“Tis Pity”,“type”:“episode”}}}

i want the label data and put it in a virtual device.

Thanks in advance

I save JSON data in Vera in the PLTS, PLEG, and PLC plugins.
There is a JSON parser on Vera.

It can’t read all the data it writes!
Others have loaded their own JSON parsing package as part of their plugin.
