XML Object in AS3 stuck in memory?

Hey all. So I’m not a newbie when it comes to Flash development, but I am trying to update my chops by assimilating AS3. The thing that has me perplexed at the moment is that the new XML object seems to keep the xml data in memory somewhere and never updates it when the xml document changes. Isn’t easily changed data the point of having it located external to a Flash application? So my question is, how does one do this so that if the xml data changes, the application reads the changes and doesn’t keep the xml data in memory (if that is in fact the case)? Can I flush the memory somehow? Or what is really happing here? :stare:
