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.
