Use the toXMLString() method to return a string representation of the XML object regardless of whether the XML object has simple content or complex content.

Do not create large XML objects in memory to avoid out-of-memory conditions. When dealing with XML streams use XMLStreamReader and XMLStreamWriter. The following example shows how:

 var id : String = "p42";
 var pname : String = "a product";

 // use E4X syntax
 var product : XML =
   <product id={id}>
     <name>{pname}</name>
     <shortdesc></shortdesc>
   </product>;

 product.shortdesc = "a fine product";
 product.longdesc = "this is a fine product";

 var xmlString = product.toXMLString();

 fileWriter.write(xmlString);
 

The code above will write the following to file:

 <product id="p42">
   <name>a product</name>
   <shortdesc>a fine product</shortdesc>
   <longdesc>this is a fine product</longdesc>
 </product>
