Large XML data in Flash player have lots of issues. I thoroughly investigated the issue and I posted a bug here (https://bugs.adobe.com/jira/browse/SDK-15113). It shows that you can't repeatedly download more than 3M of xml and have your browser stable, it will crash. There are leaks when you convert string to XML , when you save XML to local storage, maybe more issues but I stopped there.
If you want to have 25Mb XML loading/saving more than once, you should change your strategy. Download/save in chunks less than 1Mb (I know, sucks!). Basically, avoid var a:XML = XML(str); where str is >1Mb. If you have flexible server, maybe use AMF and download binary object, or use JSON (I can't guarantee the stability of those approaches as I didn't try them). As for the UI, the best thing to do for your tree is to have a virtual tree, i.e a tree that dynamically display data when you open the node. This way, the tree doesn't hold duplicate data, just reference. Anyway, looks like any solution you will try is not simple, so good luck, and keep us in touch with your solution.
