load html page into flex textarea

Answer 1

I have done like this b4 but with flash CS3 by using URLLoader and URLRequest so it's the same idea in flex try using this concept

public function sendSQLQuery(aspURL:String, variables:URLVariables, returnSQLXMLCallback:Function):void
     {
        var myXMLURL:URLRequest = new URLRequest(aspURL);    
        myXMLURL.data = variables;     
        myXMLURL.method = URLRequestMethod.POST;     
        var myLoader:URLLoader = new URLLoader();     
        //Define the event handlers to listen for success and failure
           myLoader.addEventListener ( IOErrorEvent.IO_ERROR, handleIOError );
           myLoader.addEventListener ( HTTPStatusEvent.HTTP_STATUS, handleHttpStatus );
           myLoader.addEventListener ( SecurityErrorEvent.SECURITY_ERROR, handleSecurityError );
           myLoader.dataFormat = URLLoaderDataFormat.TEXT;
        myLoader.addEventListener("complete", returnSQLXMLCallback);   
        myLoader.load(myXMLURL);
     }

and i recieve the returned page in XML format and then parse it

Try using the .htmlText property of your TextArea control. See here, from the Flex docs:

http://www.adobe.com/livedocs/flex/3/langref/mx/controls/TextArea.html#htmlText

That should work, but keep in mind the HTML-rendering capabilities of Flex controls are still quite rudimentary; you won't get much in the way of styling or formatting (hence the number of questions on StackOverflow on this very topic), but the basics should work for ya.

A shorthand way:

<mx:TextArea htmlText="{xmlText}" /> 
<mx:String id="xmlText" source="data.xml" />
