Unfortunately it’s not available in AS3, AS2, or JavaScript. Maybe one day there will be a port.

You may want to look at vtd-xml as the state of the art in XML processing, consuming far less memory than DOM http://vtd-xml.sf.net

Interesting. Would you mind posting your test environment (specs, OS, Flash player)?

FYI :
XML Class Time: 564
String Class Time: 3
XML Class from String Time: 13
(var $xml:XML = new XML (studentsString);)

I thought of converting the string to XML and the XML to string, but decided to keep the test pure. After all, sometimes you want the string and sometimes you want the XML, so there is no universal goal that both approaches should go toward. But you showed some interest so I tried it out. It didn’t make any significant difference in either time. I’m still seeing the exact same numbers as I listed in the article. Still, it’s good to know that these conversions are fast!

I’d be curious to see what the result is for the String route if you parse it to XML at the end: var $xml:XML = new XML (studentsString);

I cleaned up your posts (I don’t know how to put XML in comments either, but I’ll look into it) and tried out your version on the Windows environment I added to the article. The difference seemed negligible: 225-235ms compared to 229. Still, it’s a lot cleaner way of doing it, especially for this simple example.

Thanks for the tip!

Have you try :

    var student:XML = 
    <student>
      <firstName>First{i}firstName>
      <lastName>Last{i}lastName>
    student>;
    studentsXML.appendChild(student);

It does the same result but without large call of functions.
