  final executedValue = value.execute(results.toList(), passed);
  return results.isEmpty || value.isEmpty
      ? []
      : results.length > 1
          ? throw _requiresList('.replace()', results)
          : value.length == 3 &&
                  value.first is StringParser &&
                  value.last is StringParser
              ? [
                  results.first.toString().replaceAll(
                      RegExp('${executedValue.first}'),
                      '${executedValue.last}')
                ]
              : throw FhirPathEvaluationException(
                  'The function .replace() was not provided the '
                  ' proper parameters.',
                  operation: '.replace()',
                  collection: results,
                  arguments: value);
