Lithium API to create a module to get the 3 most recent posts on other server

You will need to traverse the response object to find out the data you want

Examples:

    success: function(data) {
		var resp = data.response;
		
		alert("Response status is: " + resp.status);
		alert("Response messages: " + resp.node_message_context.message.length);
		alert("First message subject : " +resp.node_message_context.message[0].subject.$);
		 
    }

 Of course the above are merely examples and should not be used in production - but it gives you an idea.
