Iterate JSON where Member Names are Data Values

See more JSON Examples

Demonstrates how to parse JSON where member names are not keywords, but instead are data values. Unicode C

void ChilkatSample(void)
    {
    BOOL success;
    HCkJsonObjectW json;
    int numMembers;
    int i;
    const wchar_t *name;
    HCkJsonObjectW jRecord;

    success = FALSE;

    json = CkJsonObjectW_Create();

    success = CkJsonObjectW_LoadFile(json,L"qa_data/json/valuesAsNames.json");

    // Imagine we have JSON such as the following:

    // {
    //   "1680": {
    //     "entity_id": "1680",
    //     "type_id": "simple",
    //     "sku": "123"
    //   },
    //   "1701": {
    //     "entity_id": "1701",
    //     "type_id": "simple",
    //     "sku": "456"
    //   }
    // }
    // 

    // This presents a parsing problem because the member names, such as "1680"
    // are not keywords.  Instead they are data values.  We don't know what they
    // may be in advance.  

    // To solve, we iterate over the members, get the name of each, ...
    numMembers = CkJsonObjectW_getSize(json);

    for (i = 0; i <= numMembers - 1; i++) {

        name = CkJsonObjectW_nameAt(json,i);

        wprintf(L"%s:\n",name);
        jRecord = CkJsonObjectW_ObjectAt(json,i);

        wprintf(L"entity_id: %s\n",CkJsonObjectW_stringOf(jRecord,L"entity_id"));
        wprintf(L"type_id: %s\n",CkJsonObjectW_stringOf(jRecord,L"type_id"));
        wprintf(L"sku: %s\n",CkJsonObjectW_stringOf(jRecord,L"sku"));
