README
Author: Joost Nijhuis <jnijhuis81@gmail.com>
A PHP Implementation for building an AST (Abstract Syntax Tree) from a JSON Path
string.
The AST is visitable and can be visited by implementing a visitor (Behavioral Design Pattern Visitor).
Purposes of this library are:
- Validate JSON Path syntax and give the end user a precise error message about syntax errors
- Transform the AST into some other usable structure
- Travers AST by implementing your own visitor
More information about JSON Path can be found here.
