解析有子节点的xml字符串问题

Question

我用sax解析xml字符串，发现当有子节点的时候，子节点的数据时获取不到的，谁能帮我改下代码？实现可以正常解析所有xml字符串。public static MessageData analyzeXML(String value){
MessageData md = new MessageData();
Commoditys cd = new Commoditys();
StringReader read = new StringReader(value);
InputSource source = new InputSource(read);
    SAXBuilder saxb = new SAXBuilder();   
//     List result = null;
    Map<String,String> map = new HashMap<String,String>();
    try {         
//             result = new ArrayList();    
            Document doc = saxb.build(source);   
            Element root = doc.getRootElement();      
            List node = root.getChildren();   
            Element et = null;   
            for (int i = 0; i < node.size(); i++) {   
            et = (Element) node.get(i);
            List subNode = et.getChildren();    
               
            Element subEt = null;   
            for (int j = 0; j < subNode.size(); j++) {                 
                subEt = (Element) subNode.get(j); 
                map.put(subEt.getName(), subEt.getText());   
            }            
//             if (map.size() > 0)   
//                result.add(map);   
            }
            
    } catch (JDOMException e) {         
         e.printStackTrace();   
    } catch (IOException e) {   
         e.printStackTrace();   
    }   
md.setBarCode(map.get("BarCode"));
md.setOrderNumber(map.get("OrderNumber"));
md.setRecipientName(map.get("RecipientName"));
md.setRecipientAddress(map.get("RecipientAddress"));
md.setRecipientCode(map.get("RecipientCode"));
md.setRecipientPhone(map.get("RecipientPhone"));
md.setPayment(map.get("Payment"));
md.setWeight(map.get("Weight"));
md.setPostage(map.get("Postage"));
md.setServiceCharge(map.get("ServiceCharge"));
md.setPostagePostPaidFlag(map.get("PostagePostPaidFlag"));
md.setMailType(map.get("MailType"));
md.setOrderFlag(map.get("OrderFlag"));
md.setDescription(map.get("Description"));
md.setSign(map.get("Sign"));
md.setMerchantPublicCert(map.get("MerchantPublicCert"));
cd.setCommodityName(map.get("CommodityName"));
cd.setCommodityCode(map.get("CommodityCode"));
cd.setQuantity(map.get("Quantity"));
cd.setUnitPrice(map.get("UnitPrice"));
md.setCommoditys(cd);
return md;
}
发现当xml字符串如下时，cd.setCommodityName(map.get("CommodityName"));
cd.setCommodityCode(map.get("CommodityCode"));
cd.setQuantity(map.get("Quantity"));
cd.setUnitPrice(map.get("UnitPrice"));这几个是空值的，也就是没解析到。StringBuffer xml  = new StringBuffer();
xml.append("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
xml.append("<Result xmlns=\"http://www.fiorano.com/fesb/activity/DBQueryOnInput2/Out\">");
xml.append("<Content>");
xml.append("<BarCode>424244244 </BarCode >");
xml.append("<OrderNumber>42244</OrderNumber >");
xml.append("<RecipientName>ffff</RecipientName>");
xml.append("<RecipientAddress>gggg</RecipientAddress>");
xml.append("<RecipientPhone>332323</RecipientPhone>");
xml.append("<RecipientCode>收件人fggf</RecipientCode>");
xml.append("<Payment>1452 </Payment>");
xml.append("<Weight>24</Weight>");
xml.append("<Postage>145</Postage>");
xml.append("<ServiceCharge>354</ServiceCharge>");
xml.append("<PostagePostPaidFlag>1</PostagePostPaidFlag>");
xml.append("<MailType>0</MailType>");
xml.append("<OrderFlag>2</OrderFlag>");
xml.append("<Commoditys>");
xml.append("<Commodity>");
xml.append("<CommodityName>fgf</CommodityName>");
xml.append("<UnitPrice>758</UnitPrice>");
xml.append("<Quantity>50</Quantity>");
xml.append("<CommodityCode>dfdf23323</CommodityCode>");
xml.append("</Commodity>");
xml.append("</Commoditys>");
xml.append("<Description>附加说明</Description>");
xml.append("</Content>");
xml.append("</Result>");
MessageData md = Parser.analyzeXML(xml.toString());

貌似少了一层循环，这样试试Element et = null; 
for (int i = 0; i < node.size(); i++) {   
et = (Element) node.get(i);
List subNode = et.getChildren();   
Element subEt = null;   
for (int j = 0; j < subNode.size(); j++) {                        
subEt = (Element) subNode.get(j); 
if(subEt.getName().equals("Commoditys")) {
List subNode_ = et.getChildren();
Element subEt_ = null;   
for (int n = 0; n < subNode_.size(); n++) {                        
subEt_ = (Element) subNode_.get(n);
map.put(subEt_.getName(), subEt_.getText());
}
}
map.put(subEt.getName(), subEt.getText());   
}
}
