写code, 我基本没有遇到system design

1. public static String getMsgType1(String message) {
   
2.     //Simply read the file and try to convert it to a DOM. If this does not fail you got a valid XML file.
   
3.     //File file = new File("/path/my.xml");
   
4.     try{
   
5.       StringBuilder st = new StringBuilder(message);
   
6.       DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
   
7.       DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
   
8.       Document doc = dBuilder.parse(st);
   
9.       log.info("Message is a valid XML.");
   
10.     }catch(IOEception e) {
    
11.       log.info("Message is not valid XML.");
    
12.     }
    
13.     return null;
    
14.   }
