Mapping the extracted information
W4F represents the extracted information as Nested String Lists
- NSL :: null
| String
| list(NSL)
Leaf nodes create strings.
Lists are created by index ranges, forks and regex operators.
Invalid paths create null.
NSLs are anonymous and expressive enough to capture complex structures
NSLs can be manipulated via an API.
However they are not suitable for high-level application development.
