Re: [Flashcoders] Which Data Structure is good for this?
I think Steven has already sent you the XML2AS code which is great. You could also try the XMLParser class I wrote which is similar but adds a few features. You can basically throw your XML document at it and it'll spit back an object with properties & arrays that follow the naming convention from your original XML document which makes it a lot easier to get at the data (in my opinion at least). It'll retain your hierarchy too. Snag it at: http://www.greensock.com/ActionScript/XMLParser Hope it helps.

The XML file has a structure like this: [snipped] The e4x functions make dealing with XML objects s nice that I don't see any particular reason to convert it to something else.

RE: [Flashcoders] Which Data Structure is good for this?
Thanks Steven! Forgot to mention that I'm using AS3. I will try to write
your method in AS3 and see if it fits my needs.
Cheers,
Sascha
