                           <dairy color="White">Milk</dairy>
                         </example>;
                         
       delete example.fruit.@color;
       
       delete example.dairy;
       
       delete example.vegetable.text(  )[0];
       
       trace( example );

   }
 }

}

       </source>
   
  

Removing XML Nodes

   <source lang="java">

package{

 import flash.display.Sprite;
 
 public class Main extends Sprite{
   public function Main(){

       var movieList:XML = <movieList>
                               <listName>My favorite movies</listName>
                               <movie id="123">
                                   <title>Titus</title>
                                   <year>1999</year>
                                   <director>J T</director>
                               </movie>
                               <movie id="456">
                                   <title>Rushmore</title>
                                   <year>1998</year>
                                   <director>W A</director>
                               </movie>
                               <movie id="789">
                                   <title>Hall</title>
                                   <year>1977</year>
                                   <director>Woody Allen</director>
                               </movie>
                          </movieList>;
       delete movieList.movie[2];
       trace(movieList.movie);
   }
 }

}

       </source>
   
  

The delete operator works for other types of nodes as well, such as attributes.

   <source lang="java">

package{

 import flash.display.Sprite;
 
 public class Main extends Sprite{
   public function Main(){

       var movieList:XML = <movieList>
                               <listName>My favorite movies</listName>
                               <movie id="123">
                                   <title>Titus</title>
                                   <year>1999</year>
                                   <director>J T</director>
                               </movie>
                               <movie id="456">
                                   <title>Rushmore</title>
                                   <year>1998</year>
                                   <director>W A</director>
                               </movie>
                               <movie id="789">
                                   <title>Hall</title>
                                   <year>1977</year>
                                   <director>Woody Allen</director>
                               </movie>
                          </movieList>;
       var tron:XML = movieList.movie[2];
       delete tron.@*;
       trace(tron);
       
       tron.id = 222; // Adding the id attribute back.
       trace(tron);
   }
 }

}

       </source>
   
  

To delete all the items in the XMLList, use a for loop and iterate over the items in reverse order

   <source lang="java">

package{

 import flash.display.Sprite;
 
 public class Main extends Sprite{
   public function Main(){

       var example:XML = <example>
                           <fruit color="red" name="Apple" />
                         </example>;
       
       var attributes:XMLList = example.fruit.@*;
       
       for ( var i:int = attributes.length(  ) - 1; i >= 0; i-- ) {
           delete attributes[i];
       }
       trace( example );
   }
 }

}

       </source>
