我们拿支付宝对账的订单来解析。

上面的截图是，支付宝对账结果的一部分数据。下面我写下具体的代码：

private Map<String, Object> xmlToMap(InputStream inputStream){Map<String, Object> resultMap = new HashMap<String, Object>();SAXReader reader = new SAXReader();List<AccountQueryAccountLogVO> accountQueryAccountLogVOs = new ArrayList<AccountQueryAccountLogVO>();try {org.dom4j.Document doc = reader.read(inputStream);//获取alipay节点以下的所有子节点List<Node> nodeList = doc.selectNodes("//alipay/*");for (Node node : nodeList) {String nodeName = node.getName();//判断是否有成功标示if ("is_success".equals(nodeName) && node.getText().equals("T")) {//解析响应的内容信息List<Node> tempList = doc.selectNodes("//response/account_page_query_result/*");if (tempList != null && tempList.size() > 0) {for (Node node1 : tempList) {String tempNodeName = node1.getName();String tempNodeText = node1.getText();if ("has_next_page".equals(tempNodeName)) {LOGGER.debug("是否有下一页：{}", "T".equals(tempNodeText) ? true : false);resultMap.put("has_next_page", "T".equals(tempNodeText) ? true : false);}if ("page_no".equals(tempNodeName)) {LOGGER.debug("当前页码：{}", tempNodeText);resultMap.put("page_no", tempNodeText);}if ("page_size".equals(tempNodeName)) {LOGGER.debug("每页显示条数：{}", tempNodeText);}if ("account_log_list".equals(tempNodeName)) {List<Node> accountLogs = node1.selectNodes("AccountQueryAccountLogVO");for (Node accountLog : accountLogs) {AccountQueryAccountLogVO accountQueryAccountLogVO = new AccountQueryAccountLogVO();//商户订单号String merchant_out_order_no = accountLog.selectSingleNode("merchant_out_order_no").getText();//支付宝交易号String trade_no = accountLog.selectSingleNode("trade_no").getText();//只匹配客户端充值的信息if (pattern.matcher(trade_no).matches()) {//todo}if (StringUtils.isNoneBlank(merchant_out_order_no)) {accountQueryAccountLogVO.setMerchant_out_order_no(merchant_out_order_no);}if (StringUtils.isNotBlank(trade_no)) {accountQueryAccountLogVO.setTrade_no(trade_no);}accountQueryAccountLogVOs.add(accountQueryAccountLogVO);}resultMap.put("rows", accountQueryAccountLogVOs);}}}}}} catch (Exception e) {LOGGER.error("解析遇到bug{}", e.getMessage());}LOGGER.debug("==============解析xml结束,共收集客户端账单条数：{}", accountQueryAccountLogVOs.size());return resultMap;
}
