If we have the next json:
{ "a" : 1.0, "b" : 2.0 }
then we can get the value "a" using getReal("a").
How to get the value "a" for example of the first element "list" for the following example:
{ "list" : [ { "a" : 1, "b" : 2 }, { "a" : 2, "b" : 1 } ] }
In the examples there is a case when an array of values is considered, but such a case is not considered, thanks.
