Well, you can override the XML.onData. This is fired before XML's onLoad, and it'll give you the raw XML string data, unparsed. You can then manually parse this.
Are these XML files created yet? Like, you say Excel document. If you can, creating a dictionary file that points to a series of XML files is tons better than 1 big beast. The problem is, even XML.onData still has that honkin' string in it, and using the String methods on it will still chug. Your best bet is to load in the index file, and only load those smaller files. Even if the the "smaller" file consists of thousands of records, you can simply wait a frame after she loads, use a String.indexOf on a certain node, say "<record>" and repeat over a series of frames to record indices of where all the nodes are. In the next pass, you could then break it up into chunks. Since strings are copy by value, you could make a copy of the string you want to parse, just parse that chunk, convert to something meaningful like an array full of objects, discard the string, and repeat on the next frame. You could even save those objects you've created as sharedobjects, eliminating them from memory. ----- Original Message ----- From: "Jonathan Clarke" <[EMAIL PROTECTED]> To: "Flashcoders mailing list" <[email protected]> Sent: Thursday, January 05, 2006 10:17 PM Subject: Re: [Flashcoders] Massive XML files and Flash Thanks Jester, but databases are not my forte, to do it quickly I'd like to just use ActionScript only.
