XML and FLash Action Script Problems

Hopefully someone can help me with this, since I have reached a point of frustration I"m sure you are all familiar with. I have been trying to create a flash piece that displays a Yahoo! Map that can be easily navigated and displays custom markers which are placed on specific locations on the map according to info being fed from the XML. I was able to do all of this with a very simple XML but in trying to adjust my action script to suit a more complex XML have failed miserably.

Currently my file flash_map.swf is pulling in an XML file called ‘locations.xml’. I need it to achieve the same affect by pulling in data from “search_results.xml”. All files have been provided in case anyone wants to help me out, it would be greatly appreciated.
