Flash / Flex / ActionScript/String/replace

Remove characters or words instead of replacing them

 
package{
  import flash.display.Sprite;
  
  public class Main extends Sprite{
    public function Main(){
        var example:String = "This is a cool sentence.";
        trace( example.replace( "cool ", "" ) );
    }
  }
}

Remove the
tags and replace them with newline characters ("\n")

 
package{
  import flash.display.Sprite;
  
  public class Main extends Sprite{
    public function Main(){
        var example:String = "This is<br>a sentence<br>on 3 lines";
        
        trace( example.split( "<br>" ).join( "\n" ) );
    }
  }
}

Removing and Replacing Characters and Words

 
package{
  import flash.display.Sprite;
  
  public class Main extends Sprite{
    public function Main(){
        var example:String = "This is a cool sentence."
        
        trace( example.replace( " is ", " is not " ) );
    }
  }
}

replace(reCase, "\\$2, $1")

 
package{
  import flash.display.Sprite;
  
  public class Main extends Sprite{
    public function Main(){
        var reCase:RegExp = new RegExp("(\\w+) (\\w+)", "gi");
        var sVal = new String("ActionScript Bible");
        var sRepl = sVal.replace(reCase, "\\$2, $1");
        trace(sRepl);

    }
  }
}

Replace with Regular Expression

 
package{
  import flash.display.Sprite;
  
  public class Main extends Sprite{
    public function Main(){
        var introduction:String = "My name is A!";
        trace(introduction.replace(/my name is (\w+)/gi, "$1 is my name"));
    }
  }
}

Replacing

 
package{
  import flash.display.Sprite;
  
  public class Main extends Sprite{
    public function Main(){
        var reCase:RegExp = new RegExp("shoot|crud|darn", "gi");
        var sVal = new String("Shoot! More darn regular expression crud!");
        var sRepl = sVal.replace(reCase, "%#@$");
        trace(sRepl);
    }
  }
}

Use replace with while loop

 
package{
  import flash.display.Sprite;
  
  public class Main extends Sprite{
    public function Main(){
        var example:String = "It"s a bird, it"s a plane, it"s ActionScript Man!";
        var replaced:String = example; // Initialize replaced with the original text
        
        while ( replaced.indexOf( "it"s" ) != -1 ) {
          replaced = replaced.replace( "it"s", "it is" );
        }
        
        replaced = replaced.replace( "It"s", "It is" );
        
        trace( replaced );
    }
  }
}

Within the replacement string (the second parameter), you can use special values $1 to $9 to indicate the first nine remembered substrings

 
package{
  import flash.display.Sprite;
  
  public class Main extends Sprite{
    public function Main(){
        var reCase:RegExp = new RegExp("(\\w+) (\\w+)", "gi");
        var sVal = new String("ActionScript Bible");
        var sRepl = sVal.replace(reCase, "$2, $1");
        trace(sRepl);
    }
  }
}
