Question

Is it possible to get an XML file (not HTML) from a server, add/remove/edit particular parts of it with client-side JavaScript, and then send it back to the server to save it? JSON or any other markup/data interchange format works too.

Answer 1

Yes. Using jQuery…

$.get("myGetUrl.php", function(data) {
  var xml = $(data);

  xml.find("myNode").text("newValue");

  $.post("myPostUrl.php", xml, function(resp) {
    alert(resp);
  }, "xml");
});
