This does sound like server oriented work. However, If the OP is only going to search the data, and not attempt to display it all in a tree, it might not be unreasonable. AS3 is very fast for in-memory stuff, the slow part is the rendering.
Assuming you are certain you want to do this on the client, then you do not need to do anything special. XMLListCollection is optional, and XMLList is inherent in any e4x expression result. Just get the data as XML(resultFormat="e4x"), and using a result handler, put the data into an instance-level variable,and execute the e4x query against that var. I suggest you test this with the full-data load before you get too far into the implementation. Really does sound like server work...

I don't think you want to load 25MB of data into Flash Player... bad things will probably happen. Putting that much into tree a would almost certainly be a very bad scene.

The actual XML file is about 25MB, and I have to download it weekly (from the National Do Not Call Registry). So, I thought I had to do something more elegantly (with HTTPService and XMLList and/or XMLListCollection) to read in that large XML file. > > And, again, I can read in and display the contents of the XML file, but I just can't search through the contents of the tree control anymore when I switch from a simple <mx:XML> tag to either the XMLList and/or XMLListCollection. > > Any hints?
