JSON FindRecordString Example

See more JSON Examples

Demonstrates the FindRecordString method for searching an array of JSON records. The data used in this example is available at JSON sample data for FindRecordString.

Note: This example requires Chilkat v9.5.0.63 or later.

Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // Note: This example requires Chilkat v9.5.0.63 or later.
  final json = CkJsonObject();

  json.loadFile('qa_data/json/qb_accounts.json');

  // A sample of the content of qb_accounts.json is shown at the bottom of this example.
  // The idea of FindRecordString is to search for a record matching one field,
  // and then return the value of another field.

  // For example, we want to find the "Id" for the record where Name = Advertising

  final arrayPath = 'QueryResponse.Account';
  final relativePath = 'Name';
  final value = 'Advertising';
  final caseSensitive = true;
  final retRelPath = 'Id';

  final String id;
  try {
    id = json.findRecordString(arrayPath, relativePath, value, caseSensitive, retRelPath);
  } on ChilkatException {
    print('Record not found.');
    return;
  }

  // The Id should be 7.
  print('The Id of the Advertising account is $id');
