cl_sxml_string_reader

While searching on how to validate a given JSON string, I found two options. The first simply returns a Boolean value, the second also returns information about what could be wrong.

DATA(lv_json) = '{'
             &&      '"employee": {'
             &&           |"name" : "Max", |
             &&           |"age"  : 43,    |
             &&      '}'
             && '}'.


" option 1:
DATA(is_valid) = /ui5/cl_json_util=>is_wellformed( lv_json ).

" option 2: 
DATA(lo_reader) = cl_sxml_string_reader=>create( cl_abap_codepage=>convert_to( lv_json ) ).
TRY.
    lo_reader->next_node( ).
    lo_reader->skip_node( ).
  CATCH cx_sxml_parse_error INTO DATA(lx_parse_error).
    WRITE lx_parse_error->get_text( ).
ENDTRY.
