Change is made to the original document

 
package{
  import flash.display.Sprite;
  
  public class Main extends Sprite{
    public function Main(){
        var novel:XML = <BOOK ISBN="0000000000">
            <TITLE>ActionScript</TITLE>
            <AUTHOR>J, J</AUTHOR>
            <PUBLISHER>Books Ltd</PUBLISHER>
          </BOOK>;
          
        trace(novel);
        var children:XMLList = novel.*;
        trace(children);
        
        delete novel.PUBLISHER;
        trace(novel);  
        trace(children); 
    }
  }
}

" character can be used to delimit an attribute value in an XML literal, it is converted to the " character

 

package{
  import flash.display.Sprite;
  
  public class Main extends Sprite{
    public function Main(){
        var p:XML = <p align="left"/>;
        trace(p.toXMLString(  ));  // Displays: <p align="left"/>
    }
  }
}

Converting Strings to XML

 

package{
  import flash.display.Sprite;
  
  public class Main extends Sprite{
    public function Main(){
        var dialog:String = "Lorem ipsum dolor sit amet";
        var XMLString:String = "<dialog>" + dialog + "</dialog>";
        var xml:XML = XML(XMLString);
        trace(xml.text()); // Displays: Lorem ipsum dolor sit amet

    }
  }
}

Converting XML to Strings: The toString() method for XML objects will usually display the contents of an XML element including any tags.

 

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>;
        trace(movieList);
    }
  }
}

Creates a variable refering to xml data child nodes

 
package{
  import flash.display.Sprite;
  
  public class Main extends Sprite{
    public function Main(){
        var novel:XML = <BOOK ISBN="0141182806">
          <TITLE>Ulysses</TITLE>
          <AUTHOR>Joyce, James</AUTHOR>
          <PUBLISHER>Penguin Books Ltd</PUBLISHER>
        </BOOK>
        
        var children:XMLList = novel.*;
        trace(children);
    }
  }
}

Creates the same XML hierarchy and dynamically specifies all element names, attribute names, attribute values, and element contents.

 
package{
  import flash.display.Sprite;
  
  public class Main extends Sprite{
    public function Main(){
        var rootElementName:String = "BOOK";
        var rootAttributeName:String = "ISBN";
        var childElementNames:Array = ["TITLE", "AUTHOR", "PUBLISHER"];
        var bookISBN:String = "0000000000";
        var bookTitle:String = "ActionScript";
        var bookAuthor:String = "J, J";
        var bookPublisher:String = "Books Ltd";
        var novel:XML = <{rootElementName} {rootAttributeName}={bookISBN}>
            <{childElementNames[0]}>{bookTitle}</{childElementNames[0]}>
            <{childElementNames[1]}>{bookAuthor}</{childElementNames[1]}>
            <{childElementNames[2]}>{bookPublisher}</{childElementNames[2]}>
          </{rootElementName}>;
          
  
        trace(novel); 
    }
  }
}

Invoke string method on XML data

 
package{
  import flash.display.Sprite;
  
  public class Main extends Sprite{
    public function Main(){
        var novel:XML = <BOOK ISBN="0000000000" INSTOCK="false">
            <TITLE>ActionScript</TITLE>
            <AUTHOR>J, J</AUTHOR>
            <PUBLISHER>Books Ltd</PUBLISHER>
          </BOOK>;
        
        if (novel.@INSTOCK.toLowerCase(  ) == "false") {
          trace("Not Available!");
        } else {
          trace("Available!");
        }

    }
  }
}

Using + and += Operators to combine XML Nodes

 

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 anotherMovie:XML = <movie id="222">
                                  <title>Tiger</title>
                                  <year>1982</year>
                                  <director>S L</director>
                               </movie>;
        
        This may be the simplest way to add data to an XML structure.
        movieList.movie += anotherMovie;
        trace(movieList);

    }
  }
}
