Save to XML file without user prompt dialog in action script 3?

How can save data into a XML file without user prompt dialog in Action Script 3?

I'm writing an simple application (with adobe flash) that runs on client PC and 开发者_高级运维save user state data in XML file in same directory of app. When i use FileReference it shows a user dialog for saving file. Is there any class to save just XML data directly into XML file?

I think writing just XML (text plane) data couldn't make any security problems? :-?

Im amazed noone has posted this already. Load the xml file into memory using URLLoader, making sure the dataFormat is URLLoaderDataFormat.TEXT, then write it to a file using a filestream.

Working code is posted below

Hope it helps

private function loadConfigFromServer():void{
    var request:URLRequest = new URLRequest(serverConfigXmlLocation);
    configLoader = new URLLoader();

    configLoader.addEventListener(Event.COMPLETE, configLoadCompleteHandler);
            configLoader.addEventListener(IOErrorEvent.IO_ERROR, configLoadIOErrorEventHandler);
    configLoader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, configLoadSecurityErrorEventHandler);

    configLoader.dataFormat = URLLoaderDataFormat.TEXT;
    configLoader.load(request);

}


 private function configLoadCompleteHandler(event:Event):void{
     configLoader.removeEventListener(Event.COMPLETE, configLoadCompleteHandler);
     configLoader.removeEventListener(IOErrorEvent.IO_ERROR, configLoadIOErrorEventHandler);
     configLoader.removeEventListener(SecurityErrorEvent.SECURITY_ERROR,   configLoadSecurityErrorEventHandler);
     trace("config download complete");
     var fs:FileStream = new FileStream();
     try{
         fs.open(new File(localConfigXmlLocation), FileMode.WRITE);
         fs.writeMultiByte(configLoader.data, "unicode");
     }catch(error:IOError){
         trace("IOError saving config xml");
     }catch(error:SecurityError){
         trace("SecurityError saving config xml");
     }finally{
         fs.close();
         parseLocalConfig();
     }
}

The only real way to save data without a dialog coming up is through the SharedObject class. Provided you don't need to edit the XML externally, it should be fine, you can save it.

SharedObject will put up a dialog however if you go above 100KB (i think) of data, so if your XML is getting larger than this, compress it using a ByteArray.

Compressing:

var ba:ByteArray = new ByteArray;
ba.writeUTFBytes( myXML );
ba.compress();

Uncompressing:

try
{
    ba.uncompress();
}
catch ( e:Error )
{
    trace( "The ByteArray wasn't compressed!" );
}

// set our xml data
myXML = XML( ba );

With a shared object like divillysausages described, you can save an array, or XML data, or other variables to a shared object to retrieve it later. You're only saving this data to the users computer, so it can't be used anywhere but locally on their machine again. Short answer, without a server-side language to communicate with, you cannot save data to an actual XML file if it's an-browser app or a projector.
