Hey guys…

So, my situation is like this:  
I have an XML file.  
I load the file to flash and display data.  
But this XML file can be changed by some other system, updates data,…  
Now, i want to update my data in flash also.  
What i have done is use timer and check XML file every… let’s say second.  
And i don’t wanna do that…

I just want to know what the data in XML file changed and update at that time, otherwise do nothing.

So, i was wondering if that is possible. Is it possible for AS3 to get an event or something, when XML file changes.

I know i could do that with FMS or Red5 and shared objects… but let’s say that that is not the best option in our case.

So, can I listen to changes in XML file??

If you know… please let me know… 🙂  
thanks…
