Unusual problem setting newline character in textarea

Hi:

I am not sure if you must use the import way to do the replacement work. If yes, please export the whole markup first and do the string replacement operation based on the exported one.

BTW, if you don't have to use the import way, you can just use the TLF way to set the properties. It's much easier and accurate. The following is my code scrap for your scenario:

<?xml version="1.0" encoding="utf-8"?>

<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"

   xmlns:s="library://ns.adobe.com/flex/spark"

   xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">

<fx:Declarations>

<!-- Place non-visual elements (e.g., services, value objects) here -->

</fx:Declarations>

<fx:Script>

<![CDATA[

private function click():void

{

var tf:TextFlow = myRich.textFlow;

var cSpan:SpanElement = tf.getFirstLeaf() as SpanElement;

var found:Boolean = false;

while(cSpan!=null)

{

if( cSpan.text == "Text2" )

{

found = true;

break;

}

cSpan = cSpan.getNextSibling() as SpanElement;

}

if(found)

{

cSpan.backgroundColor = "#B22300";

cSpan.text = "xxxx";

}

}

]]>

</fx:Script>
