Description
Finds and returns a TJSONValue instance located at the specified APath JSON path. Otherwise, returns nil.
Supported JSON Path Syntax
FindValue uses TJSONPathParser to parse the specified JSON path.
TJSONPathParser implements a subset of the JSON path specification defined by Stefan Göessner. Specifically, supported elements are child operators (.) for objects and subscript operators ([]) for arrays. These operators do not support special expressions, they only support actual values.
This is an example of a JSON path that TJSONPathParser supports: "store.books[0].title".
