How can I save the modified data to the same xml file after loading from that external xml file in ActionScript3.
Is there exist any function or method or any way to save the modified data again in the same file from which it was loaded.
import flash.net.URLRequest;
var myXML:XML = new XML();
var XML_URL:String = "sample.xml";
var myXMLURL:URLRequest = new URLRequest(XML_URL);
var myLoader:URLLoader = new URLLoader(myXMLURL);
myLoader.addEventListener("complete", xmlLoaded);
function xmlLoaded(event:Event):void
{
myXML = XML(myLoader.data);
trace("Data loaded.");
trace(myXML); //showing output of just loaded xml file.
//process of adding new child node or property.
var newnode:XML = new XML();
newnode =
<student >
<sname srno="2">mm</sname>
<father tax="no">
<fname>Ratan</fname>
<focc>business man</focc>
<mobno>9928946899</mobno>
</father>
</student>;
myXML = myXML.appendChild(newnode);
trace(myXML); //showing o/p after being the child-node appended.
}
where the sample.xml file located in the same working path, contains only the following data.-
<data>
<student srno="1" class="5" rollno="1">
<sname>Rohan Jain</sname>
<father tax="yes">
<fname>Ronak Jain</fname>
<focc>teacher</focc>
<mobno>9928946899</mobno>
</father>
</student>
</data>
If you're building a browser based application; nothing you can do on the client will save the file to a specific name and location. You'll have to send your updated doc to the server for saving. It is easy to write a service to do this in most server side languages I have dealt with.
If you want to save the file to the client machine; you can do so using FileReference.save(). However, this requires user input and there is no way to guarantee what the user will name the file or where they'll put it.

I am trying to synchronize a remote model with local changes.
My idea is to process changes similar to the graphModel documentation
function notifyListener(sender, event){
var codec = new mxCodec();
var changes = event.getProperty('edit').changes;
var nodesXml = [];
for (var I=0; I < changes.length; I++) {
var c = codec.encode(changes[I];
var cXml = mxUtils.getXml(c);
nodesXml.push(cXml);
}
};
graph.model.addListener(mxEvent.NOTIFY, notifyListener);
However the resulting XML data does only contain a element of ( in case of drag operation) mxGeometryChange;
e.g.
There is no more information; without a reference to the initial cell id I cannot reprocess this xml into the remote model.
I surely miss some information in the xml encoding process; but I don't see it.
Can you help out here ?
I’m using the following AS3 code to write and read data in two arrays to a local file, using Animate CC 2019 on Windows 10 and AIR 30.0 for Desktop/Flash (.swf) publishing settings. I use two input text boxes, input1 & input2, to add new data to the arrays.
When I test the FLA, the data file created has a .sol extension and is placed in a folder path:
C:\Users\username\AppData\Roaming\FLA filename\Local Store#SharedObjects\FLA filename.swf\
If I publish and install the program using an .air installer package, the exact same file, in the same folder path, is also accessed by the installed version of the program. Same location is used if I install on another computer running Windows 7, so the file location seems pretty consistent.
Question:
How can I force the code to save to a different location on the local hard drive on Windows? For example, in the documents folder or to create a new folder on the system drive and save the file there? Or, even better, prompt the user to choose the folder and file himself?
Please consider I’m looking for an answer using SharedObject, if possible, and not alternative methods like URLLoader, File, FileStream, FileMode. The reason is this way I can store multiple array contents in a file, without having to deal with the in-file data arrangement. So, I can read back the data for each array easily as shown below.
Thanks in advance
This is the code I use to access the local file:
var datavariable:SharedObject = SharedObject.getLocal("filiename");
var data1:Array = new Array ();
var data2:Array = new Array ();
btn_read.addEventListener(MouseEvent.CLICK, readfromfile);
btn_write.addEventListener(MouseEvent.CLICK, writetofile);
btn_new.addEventListener(MouseEvent.CLICK, newentry);
//To add new data from input text boxes to the arrays:
function newentry(e:Event):void
{
data1.push(input1.text);
data2.push(input2.text);
}
//To write to the local file:
function readfromfile(e:Event):void
{
data1 = datavariable.data.d1
data2 = datavariable.data.d2
}
//To read from the local file:
function writetofile(e:Event):void
{
datavariable.data.d1 = data1
datavariable.data.d2 = data2
datavariable.flush();
}
I don't know of a way of changing the shared object storage location. That mechanism is designed to be abstracted out from the developer.
Since you are using AIR, you can actually forget shared objects, and just write your own files anywhere your app has permission to do so. You can do this using the same format as shared object and don't have to worry about in file data arrangement (you save an object, you read back an object - just like Shared Object does), the only difference is you load/save the file where you choose.
Here is an example:
function writetofile(e:Event):void
{
//create an object that holds your data, this will act the same as the 'data' value of a shared object
var saveObject = {
d1: data1,
d2: data2
}
//using the File and FileStream classes to read/save files
var file:File = File.applicationStorageDirectory.resolvePath("saveData.data"); //or where and whatever you want to store and call the save file
var fileStream:FileStream = new FileStream();
fileStream.open(file, FileMode.WRITE);
fileStream.writeObject(saveObject); //write the object to this file
fileStream.close(); //close the File Stream
}
function readfromfile(e:Event):void
{
var file:File = File.applicationStorageDirectory.resolvePath("saveData.data");
var fileStream:FileStream = new FileStream();
fileStream.open(file, FileMode.READ);
var savedObject = fileStream.readObject();
fileStream.close();
data1 = savedObject.d1;
data2 = savedObject.d2;
}
If you want to save complex objects (objects that aren't primitives), you need to register the class first. This goes for shared objects as well. See this answer for example of that.
My requirement is to save a bunch of files (more than 500) in a single zip file locally using FileReference. I am using ASZip to zip the files. Now the problem is if the number of files are more, then I am not even getting Save as dialog box.
I have tried different combinations of data to see whether it is number of files or file size limitation, but it looks like the script automatically stops (irrespective of number of files), if it can't give me the output within a minute.
This is the code that I am using
//*****test code
var myZip:ASZip = new ASZip (CompressionMethod.GZIP);
var myByteArray:ByteArray = new ByteArray();var pdfFile:PDF;
var newPage:Page;
var printPage:BorderContainer;
for (var i:int=0;i<330;i++)
{
printPage = new BorderContainer();
printPage.visible = false;
printPage.x=0;
printPage.y=0;
printPage.includeInLayout = false;
printPage.width = 816+10;
printPage.height = 1056+23;
this.addElement(printPage);
pdfFile = new PDF(Orientation.PORTRAIT, Unit.INCHES, Size.A3 );
pdfFile.setDisplayMode( Display.FULL_PAGE,Layout.SINGLE_PAGE );
newPage = new Page ( Orientation.PORTRAIT,Unit.INCHES,new Size([816+10,1056+10],"MyFavoriteSize",[8.5+10,11+10],[816/0.125,1056/0.218]));
pdfFile.addPage(newPage);
pdfFile.beginFill(new RGBColor(0xFFFFFF));
pdfFile.textStyle(new RGBColor(0x000000));
pdfFile.addImage(printPage,null,-0.5,-0.5,8.5+4,11.5+4);
myByteArray = pdfFile.save(org.alivepdf.saving.Method.LOCAL);
myZip.addFile(myByteArray,i + ".pdf");
}
Can you please let me know what can be done to fix this issue?
Thanks,
Satish.
i need to write some XML using AIR from Flash CS5.5
My code works, but i dont know how to write some html tags without flash converting < to ; & gt;
I want to write HTML code for a .
How can i achieve that?
This is the type of code i am using, im working into an AIR from Flash CS5.5
Everything works fine except i dont get the "<" but the ;& gt; in the outputfile and the same for many of the HTML signs like > etc.
function SaveFile(event:MouseEvent){
var objs:XML = new XML( <objects /> );
var ball1:XML = <ball />.appendChild(input_text.text);
// In the input i want to write the CDATA and the HTML text dynamically each time
ball1.#xPos = 12;
ball1.#yPos = 42;
objs.appendChild( ball1 );
var vFile = File.desktopDirectory.resolvePath('file.xml');
var vStream = new FileStream();
vStream.open(vFile, FileMode.WRITE);
vStream.writeUTFBytes(objs);
vStream.close();
}
You are passing a String to the appendChild function and that's why you got your result as a "text" in your xml file. So to avoid that, you have just to pass an XML object instead of the String :
// ...
var ball1:XML = <ball />.appendChild(new XML(input_text.text));
// ...
EDIT :
To add the XML declaration to your XML file, you can use a XMLDocument like this :
// ...
objs.appendChild(ball1);
var xml_document:XMLDocument = new XMLDocument(objs.toXMLString());
xml_document.xmlDecl = '<?xml version="1.0" encoding="utf-8"?>\n';
var file = File.desktopDirectory.resolvePath('file.xml');
var file_stream = new FileStream();
file_stream.open(file, FileMode.WRITE);
file_stream.writeUTFBytes(xml_document.toString());
file_stream.close();
Hope that can help.
Let me preface this by stating that I am not terribly familiar with ActionScript, so forgive any seemingly obvious things that I may be missing.
I current have a very simple function with an AS3 application that will output a file when a button is clicked using a FileReference object as seen below :
//Example download event
public function download(event:MouseEvent):void
{
//Build a simple file to store the current file
var outputFile:FileReference = new FileReference();
//Perform a function to build a .wav file from the existing file
//this returns a ByteArray (buffer)
downloadBuffer = PrepareAudioFile();
//Attempt to build the filename (using the length of bytes as the file name)
var fileName:String = downloadBuffer.length.toString() + ".wav";
//Save the file
audioFile.save(downloadBuffer, fileName);
}
There appears to be an error occurring somewhere within here that is resulting in the File not being outputted at all when I attempt to concatenate the file name as seen above. However, if I replace the fileName variable with a hard-coded option similar to the following, it works just fine :
audioFile.save(downloadBuffer, "Audio.wav");
Ideally, I would love to derive the duration of the file based on the length of the byteArray using the following :
//Get the duration (in seconds) as it is an audio file encoded in 44.1k
var durationInSeconds:Number = downloadBuffer.length / 44100;
//Grab the minutes and seconds
var m:Number = Math.floor(durationInSeconds / 60);
var s:Number = Math.floor(durationInSeconds % 60);
//Create the file name using those values
audioFile.save(downloadBuffer, m.toString() + "_" + s.toString() + ".wav");
Any ideas would be greatly appreciated.
Where is the problem other than missing the parentheses in m.toString()?
Aren't you missing a .lenght before the division of downloadBuffer as well?
I was finally able to come up with a viable solution that required explicit typing of all of the variables (including using a separate variable for the .toString() operations) as seen below :
public function download(event:MouseEvent):void
{
//Build a simple file to store the current file
var outputFile:FileReference = new FileReference();
//Perform a function to build a .wav file from the existing file
//this returns a ByteArray (buffer)
downloadBuffer = PrepareAudioFile();
//When accessing the actual length, this needed to be performed separately (and strongly typed)
var bufferLength:uint = downloadBuffer.length;
//The string process also needed to be stored in a separate variable
var stringLength:String = bufferLength.toString();
//Use the variables to properly concatenate a file name
var fileName:String = dstringLength + ".wav";
//Save the file
audioFile.save(downloadBuffer, fileName);
}
It's bizarre that these had to explicitly be stored within separate values and couldn't simply be used in-line as demonstrated in the other examples.
