$record = array(
    'event' => $_POST['event'],
    'eventDate' => $_POST['eventDate'],
    'desc' => $_POST['desc'],
);

$doc = new DOMDocument();
$doc->load( 'calendar.xml' );

$doc->formatOutput = true;
$r = $doc->getElementsByTagName("events")->item(0);

$b = $doc->createElement("record");

$event = $doc->createElement("event");
$event->appendChild(
    $doc->createTextNode( $record["event"] )
);
$b->appendChild( $event );

$eventDate = $doc->createElement("eventDate");
$eventDate->appendChild(
    $doc->createTextNode( $record["eventDate"] )
);
$b->appendChild( $eventDate );

$desc = $doc->createElement("desc");
$desc->appendChild(
    $doc->createTextNode( $record["desc"] )
);

$b->appendChild( $desc );
$r->insertBefore( $b,$r->firstChild );

$doc->save("calendar.xml");

答

if you're using PHP5 you can use SimpleXML

答

You could edit the file as if it were a plain text file. However, you will need to make sure all elements are closed and all data is escaped correctly. If you only need to output XML this is doable, but to write a parser that can add to and modify existing XML data is a tough job. Better try to enable DOM or find an out of the box library.
