I need a script for a google map. The map should load and pull some markers from an external xml filelike this. The tricky part is that the xml file will continually change (it will be populated from a database). I want the map to check the xml file for new points and load them onto the map every 2 or 3 seconds. The end result is that a user can watch the map and see new markers popping up all the time. Please ask your questions and post estimates here. I don't want to pay too much........ Happy to consider any other methods to achieve this.
