我如何解析来自<UserProfile>的值以获取图片中的以下XML数据我是新的Java我已经编写了这段代码但不起作用

Question

点击需要解析的XML数据`

String tagName = "crminfo"; logger.info(xmlResponse); List<Map<String, Object>> parsedXmlData = DataParserUtil.parseXml(xmlResponse, tagName, fieldMapping); logger.info("parsedXmlData: " + parsedXmlData);

public static List<Map<String, Object>> parseXml(String xml, String tagName, FieldMapping fieldMapping) throws Exception {
        if (StringUtils.isBlank(xml)) {
            return new ArrayList<>();
        }

        // Remove BOM if present
        if (xml.startsWith("\uFEFF")) {
            xml = xml.substring(1);
        }
        // Remove ZWNBSP if present
        xml = xml.replaceAll("\uFEFF", "");

        DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
        Document document = builder.parse(new InputSource(new StringReader(xml)));
        NodeList nodeList = document.getElementsByTagName(tagName);
        List<Map<String, Object>> xmlObjects = new ArrayList<>();

         Map<String, String> fieldMap = fieldMapping.getFieldMap();
        for (int i = 0; i < nodeList.getLength(); i++) {
            Element element = (Element) nodeList.item(i);
            Map<String, Object> objectMap = new HashMap<>();

            // Collect all attributes and their values
            NamedNodeMap attributes = element.getAttributes();
            for (int j = 0; j < attributes.getLength(); j++) {
                Node attribute = attributes.item(j);
                String keyName = attribute.getNodeName();
                for (String jsonField : fieldMap.keySet()) {
                    String xmlField = fieldMap.get(jsonField);
                    if (StringUtils.equals(keyName, xmlField)) {
                        keyName = jsonField;
                        break;
                    }
                }
                String value = attribute.getNodeValue();
                ValueConverter converter = fieldMapping.getConverter(keyName);
                objectMap.put(keyName, converter != null ? converter.convert(value) : value);
            }
            xmlObjects.add(objectMap);
        }

        return xmlObjects;
    }

我希望像这样添加值

parsedXmlData=[{firstName=Direct_Lens_01、middleInit=、lastName=automation_test、zipCode=、国家/地区=CAN、businessUnit=、authorizedRepNo=、城市=、afslNo=、companyName=、电话=12345678、}]

但我得到 ParsedXMLData=[{}]

需要指导来改进此代码并获取值
