AjaxTop is a package that adds XML to JavaScript binding. It provides two main extension methods, the loadTag() method and the registerTag() method. The loadTag() method sends an AJAX request and applies the result to the selected object in similar fashion to the load() method. The response is expected to be XML which is automatically parsed and mapped to objects as determined by registerTag() calls. The mapped objects generate the output that is applied to the selected object. See AjaxTop for more details.
