\n parameter is not working

Question

Hello Buddies
iM having a problem in a TEXTAREA that has a bindable
variable, named desc
<mx:TextArea text="{desc}" />
following code works well and text Area detects [\n] as a NEW
LINE Parameter.
private var sDes:String = "CorelDraw\nIllustrator";
and shows it
[output]
CorelDraw
Illustrator
But when i capture abv String from a xmlfile`s tag
<desc>CorelDraw\nIllustrator</desc>
it doesnt detect it as a newline parameter and simply shows
it as
[output]
CorelDraw\nIllustrator
How can i make him understand \n parameter when it reads from
an xml file?

You can find info on special characters at xml.org and
unicode.org. Do a search for 'xml and html characters'. An example
would be for the copyright symbol... the Unicode code is 00A9, so
within an XML element you'd write &#00A9;
As far as using AS to add the newline... it will give you
greater control if the XML elements are represented as separate
values in the database field (of course assuming the XML is
dynamically assembled during a service call). However, using your
approach of directly embedding the newline character in your XML
data would be faster, especially if the data is only going to be
used by you for your specific application.
Here's a sample of how it could be handled if the XML data is
dynamically assembled with the following format and returned in e4x
resultFormat from the service call:
<servicestart>
<category>Design</category>
<imagelink>images/des.jpg</imagelink>
<tech>
<app>Photoshop</app>
<app>CorelDraw</app>
<app>Illustrator</app>
</tech>
</servicestart>
function handleResultEvent(event:ResultEvent):void
var apps:XMLList = event.result.tech.app;
var tmpStr:String = "";
if (apps.length() > 1)
for (var a:int = 0; a < apps.length() - 1; a++)
tmpStr += apps[a] + "\n";
tmpStr += apps[apps.length() - 1];
else
tmpStr += apps[0];
Technologies.text = tmpStr;
You can see how you have greater control over what you want
to do with the data. If you're the only one who will ever use this
data and only for your specific application, then the AS route is
probably overkill, but it may come in handy to know how to do it.
