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".
