This is a solution I came up with loading mutliple xml files in AS3, just within the last 30 minutes. I wanted to figure out a solution on my own instead of looking for something online. Although it is not completely dynamic, requiring multiple event types, I think it has potential to expand. Let me know what you think would help improve this, Ill be tweaking it soon.
