modify XML file with DOM

[jaejinkorean]

I'm having trouble with modifying xml file...

<?
$dom = new DomDocument();
$dom->load("fileName .xml");

?>

fileName.xml is
<classes> </classes>

then if I want to add a new class under clases
How do I do?

to get
<classes>
<class>
</class>
</classes>

thanks..

Welcome to The Scripts.
Take a look at PHP.net's documentation on XML DOM.
