                    String key = node.getNodeName();
                    String value = node.getTextContent();
                    xmlMap.put(key, value);
                }
            }

            // 打印HashMap内容
            for (String key : xmlMap.keySet()) {
                System.out.println(key + ": " + xmlMap.get(key));
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
