Help with JSON parsing

Hello all, this is the first time i use this library, i've always used xml, i need to parse this string received from a server, can anyone here please help me
I've followed Erel's tutorial but i can't seem to split the two values i need to retrieve.

{"result":[{"value":1,"i_user_id":3}]}

Click to expand...

I need to retrieve the "value" string along with the "i_user_id"

i'm sure is something simple but i can't figure it out, i can get the whole string but i need to split it into it's different values.

Thanks for the help!
