For the code in the first page I load data from the server(xml file) and I store it in an array table.

Updating only new data is possible with $.ajax. But there is no any magic method to do that. You must keep track of items changed between requests on server and return only those in JSON. Than, in success calback – go through all received elements (for instance, that could be an array with item to update as a key and value as a new value for that item) and update them.
