回答1:

Ajax works no different that it does else where execept that cross domain calls are ok with phonegap,
see my other answer

Example of jquery ajax call @ http://api.jquery.com/jQuery.ajax/
Parsing xml with javascript @ http://www.w3schools.com/xml/xml_parser.asp

$.ajax({
  url: "test.html",
  context: document.body,
  success: function(){
    $(this).addClass("done");
  }
});

Example of native javascript call
