Clickboard for Multi-line text

[ShaningYu]

See the code below.  However, when I pasted the text content, the contents are in the same line.  How to solve this problem?  I want to display the contents line by line.  Thanks.

import flash.desktop.Clipboard;
import flash.desktop.ClipboardFormats;
private var richTextEditor:mx.controls.RichTextEditor = new mx.controls.RichTextEditor();
...
private function button_click():void {
                richTextEditor.text = txtX.text;
                richTextEditor.text += '\n' + txtY.text ;
                richTextEditor.text += '\n' + txtX.text ;
                richTextEditor.text += '\n' + txtY.text ;
                System.setClipboard(richTextEditor.text);
}

P.S. SDK 4.9.0
P.S.2 It's not ArcGIS Flex API question, don't you think? Adobe learning is here

Thanks for your response.  I tested your code.  It helps to add <br> on the line.  But when it is used in clickboard, it does not make lines.  E.g. the result is like that:
<br><br>1443333.3333333333<br>370840<br>1443333.3333333333<br>370840
Still be the same line.
It is true that it not a GIS problem.

Create own utility class, and convert string as you need.

package your.package.name
{
 public class MyHelperClass
 {
  public static function convertToHtml(str:String):String
  {
   if (str != null)
   {
    while (str.search("\n") != -1) {
     str = str.replace("\n", "<br>");
    }
   }
   
   return str;
  }
  
  public static function convertFromHtml(str:String):String
  {
   if (str != null)
   {
    while (str.search("<br>") != -1) {
     str = str.replace("<br>", "\n");
    }
   }
   
   return str;
  }
 }
}

when needed just call

var someString:String = "Acura,<br>Buick,<br>Corvette,<br>Dodge";
var result:String = MyHelperClass.convertFromHtml(someString);
