Support for JSONPath / JSON Pointer / jq #63

Open mbtools opened 2 years ago

JSONPath could be a nice addition (https://restfulapi.net/json-jsonpath/):

Def:

  methods jsonpath
    importing
      iv_path type string
    returning
      value(ro_json) type if_asjon.

Example:

  lo_json->jsonpath( '$..attributes' ).

Anyone up for a JS or PHP to ABAP port? https://code.google.com/archive/p/jsonpath/downloads

Nice idea. Worth checking. Just some of commands will not be support e.g. reference from non root.

The .. is also a bit unclear - what if multiple nodes contain the attrs ? Is it the first one to select ?

mbtools commented 2 years ago

.. returns all matching attributes. '$..attributes[0]` would give you the first.

Jq would be an option, too. Looks like a package of C with dependencies, though.

sbcgua commented 2 years ago

That was just for reference. Collecting some more data about the subject. jq is definitely widespread and popular. Maybe implement it's syntax instead. Just maybe.

Also Json pointer

also JSON Pointer, which seems to be a part of JSON schema: https://datatracker.ietf.org/doc/html/draft-handrews-relative-json-pointer-01
