static Map<String, String?> extractBasicInfo(String xmlString) {
  try {
    final document = XmlDocument.parse(xmlString);

    if (!_isNfseNacional(document)) {

    }

    // Procura infDPS em qualquer profundidade
    final infDPSElements = document.findAllElements('infDPS');
    if (infDPSElements.isEmpty) {
      return {};
    }

    final infDPS = infDPSElements.first;

    return {
      'numero': _getElementText(infDPS, 'nDPS'),
