JSON - Alternative to XML in Ajax

JSON is a language of objects sent by the server.

The Client receives a Javascript object easier to control than the use of DOM or XSL.

XML Example:

<menu id="file" value="File">
 <popup>
   <menuitem value="New" onclick="CreateNewDoc()" />
   <menuitem value="Open" onclick="OpenDoc()" />
   <menuitem value="Close" onclick="CloseDoc()" />
 </popup>
</menu>

JSON Example:

{"menu": {
 "id": "file",
 "value": "File",
 "popup": {
   "menuitem": [
     {"value": "New", "onclick": "CreateNewDoc()"},
     {"value": "Open", "onclick": "OpenDoc()"},
     {"value": "Close", "onclick": "CloseDoc()"}
   ]
 }
}}
