I am integrating Google maps into our website and have a script that displays the map and directions on the page. My problem is that the info for each place is located in an external xml file but I need it to be in the same file.
Here is my code, the api key is for localhost so should work fine if anyone tries it on their own machines
and here is the xml file that I want to be on the same page as above.
