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
    
      xmlToMap(InputStream inputStream){    Map
     
       resultMap = new HashMap
      
       ();    SAXReader reader = new SAXReader();    List
       
         accountQueryAccountLogVOs = new ArrayList
        
         ();    try {        org.dom4j.Document doc = reader.read(inputStream);        //获取alipay节点以下的所有子节点        List
         
           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
          
            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
           
             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;}
