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", " "); } } return str; } public static function convertFromHtml(str:String):String { if (str != null) { while (str.search(" ") != -1) { str = str.replace(" ", "\n"); } } return str; } } } when needed just call var someString:String = "Acura, Buick, Corvette, Dodge"; var result:String = MyHelperClass.convertFromHtml(someString);
