XML.toString() returns invalid xml

I created JsonObject from String, then used XML.toString(JsonObject o) to create XML String to send response in my Servlet. But browser says it's invalid.

Can you give an example to reproduce this?

try this json:

{  
   "someObject":{  

   },
   "someObject2":{  

   },
   "someArray":{  
      "1234":[  
         {  
            "object":"data"
         }
      ]
   }
}

there is 2 error: 1st - there is no global <root> tag after conversion. I added it after conversion. 2nd - <1234> tag is incorrect, so I added to XML.java this code(416th line):

if (key.matches("\\d+")) {
                   key = "id_" + key;
               }

Given the JSON text input, the transformed XML looks reasonable to me. Please post what you think it should have been.

<someObject2></someObject2>
<someObject></someObject>
<someArray>
 <1234>
  <object>data</object>
 </1234>
</someArray>

this is a known issue. Our policy to date has been that the XML output does not guarantee valid XML. This is especially true with numeric element IDs. <1234> is not valid XML. Our suggestion to other posters has been to pre-process the JSONObject before calling XML.toString(JSONObject o)

See #294 for the most recent discussion on it.
