[flexcoders] word highlighting

[ibo]

Have anyone worked on something like this before? What I want is to highlight 
the word by changing the background color of each keyword from a 
sentence/paragraph.

Here is my code so far:

          private function applyTextHighlight(textField:UIComponent, 
listOfWordPositions:Array):void {
               var textArea:TextArea = TextArea(textField);
               var tr:TextRange = new TextRange(textArea);
               
               tr.htmlText = textArea["htmlText"];
               
               for (var i:int=0; i<listOfWordPositions.length; i++) {        
                  var metaWord:WordPositions = listOfWordPositions[i];
                  tr.beginIndex = metaWord.startIndex;
                  tr.endIndex = metaWord.endIndex;
                  tr.htmlText = formattedText(tr.text, metaWord.color);         
      
                     //tr["color"] = metaWord.color;
                     //tr["fontWeight"] = "bold";
                     //tr["fontSize"] = 12;
               }                          
          }
          
        private function formattedText(text:String, color:uint):String {
            return "<FONT style='BACKGROUND-COLOR: " + color + "'>" + text + 
"</FONT>";    
        }


TextRange seems to be very limited on how much you can format your html text so 
I'm not surprised it doesnt really fully support HTML. Any workaround to get a 
similar behavior?
Changing the text color, size and weight works though (see commented out lines).
