Flash / Flex / ActionScript/String/replace

Remove characters or words instead of replacing them

   <source lang="java">

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 ", "" ) );
   }
 }

}

       </source>
   
  

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

   <source lang="java">

package{

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

}

       </source>
   
  

Removing and Replacing Characters and Words

   <source lang="java">

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 " ) );
   }
 }

}

       </source>
   
  

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

   <source lang="java">

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);

   }
 }

}

       </source>
   
  

Replace with Regular Expression

   <source lang="java">

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"));
   }
 }

}

       </source>
   
  

Replacing

   <source lang="java">

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);
   }
 }

}

       </source>
   
  

Use replace with while loop

   <source lang="java">

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 );
   }
 }

}

       </source>
   
  

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

   <source lang="java">

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);
   }
 }

}

       </source>
