How to display regular expression text

Question

I cannot seem to get the text of a regular expression to display in a text input.  The regex is defined as:
Bindable]  
private var myRegExp:RegExp=/^.*(?=.{10,32})(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[.!@#$%*^&()+]).*$/;
In my form, I want to display the actual expression.  The code I am using to do so is:
<mx:FormItem label="regExpLabel">  
     <mx:TextInput id="regExpTextInput" text="{myRegExp}" />  
</mx:FormItem>
When I run the app, the data displayed in the regExpTextInput filed is /^.*(?=.{10,32})(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[.!@#$%*^&()+]).*$/
What I want to display is only the regular expression, not including the slashes required by Flex at the beginning and end of the string.  The data I want displayed is ^.*(?=.{10,32})(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[.!@#$%*^&()+]).*$
I tried changing my variable type to String and leaving out the beginning and ending slashes, but that did not work either.  Any thoughts?
Thanks!

Hi, I am unable to understand your requirement properly but here is one demo of the using regular expression. In this application I am allowing only those character to be enter in the Textbox which are taken as the valid filename. Hope this will help you.
I think In your requirement first of all you have to take it as string type. And the second is that use \\ before every special character if you are writing it in the script. As I have done. Pls let me know if you
Have any issue with the code below.
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Script>
      <![CDATA[
      [Bindable]
      private var regExpForFile : String
      = "0-9A-Za-z\\&\\`\\~\\!\\@\\#\\$\\%\\^\\(\\)\\-\\_\\=\\+\\]\\}\[\\'\\;\\,\\.\\{ ";
      ]]>
</mx:Script>
      <mx:VBox horizontalAlign="center" width="350">
            <mx:Label text="Enter File Name"/>
            <mx:TextInput id="fileName" width="170" height="20"  restrict="{regExpForFile}"/>
      </mx:VBox>
</mx:Application>
