Description
The first call moves the iterator to the first JSON token of the input data. Successive calls move the iterator to the next JSON token of the input data. It returns False if the JSON token where the iterator moves is the last JSON token of the input data, or True if the input data contains more tokens.
To iterate through JSON data, you usually call Next in a loop until it returns False, and read data from the properties of the iterator after every call.
You may specify a key, either an array index number or an object key name, to iterate until you reach a JSON token that matches the specified key.
