Hi!  
I want to replace “bad characters” in a text string received from an XML document but the replaced text seems to be undefined inside the for loop.

```
ActionScript Code:
[FONT=Courier New][LEFT][COLOR=#0000FF]for[/COLOR] [COLOR=#000000]([/COLOR] [COLOR=#000000] **var** [/COLOR] i:[COLOR=#0000FF]Number[/COLOR] = [COLOR=#000080]0[/COLOR]; i &lt; l; i++ [COLOR=#000000])[/COLOR]

```

[COLOR=#000000]{[/COLOR]  
[COLOR=#0000FF]String[/COLOR].[COLOR=#0000FF]prototype[/COLOR].[COLOR=#000080]replace[/COLOR] = [COLOR=#000000] **function** [/COLOR][COLOR=#000000]([/COLOR]s, z[COLOR=#000000])[/COLOR] [COLOR=#000000]{[/COLOR] [COLOR=#0000FF]return[/COLOR] [COLOR=#0000FF]unescape[/COLOR]COLOR=#000000[/COLOR]; [COLOR=#000000]}[/COLOR];  
cl.[COLOR=#000080]txt\_text[/COLOR].[COLOR=#0000FF]html[/COLOR] = [COLOR=#000000] **true** [/COLOR];  
cl.[COLOR=#000080]txt\_text[/COLOR].[COLOR=#0000FF]htmlText[/COLOR] = [COLOR=#0000FF]text[/COLOR].[COLOR=#000080]replace[/COLOR][COLOR=#000000]([/COLOR][COLOR=#FF0000]“å”[/COLOR], [COLOR=#FF0000]“å”[/COLOR][COLOR=#000000])[/COLOR];  
[COLOR=#000000]}[/COLOR]
