Check out the PHP manual:

SimpleXML: <URL:http://www.php.net/manual/en/book.simplexml. php>
DOM (PHP 5): <URL:http://www.php.net/manual/en/intro.dom.php>

If you're stuck with PHP 4:
<URL:http://www.php.net/manual/en/ref.domxml.php>

first of all, i wouldnt call each element element1 and element2 etc
just element. You can store the meta data such as a number as an
attribute instead. I'd do something like this (off the top of my head
and untested)...


$xml = <<<XML
<?xml version="1.0" encoding="UTF-8"?>
<element num="1">
<subelement1>aa </subelement1>
<subelement2>aa </subelement2>
</element>
</xml>
XML;

$dom = new DOMDocument();
$dom->loadXML($xml );

$xpath = new DomXpath($dom);

$result = $xpath->query("//element");
$result->parentNode->removeChild($r esult->item(0));

$dom->saveXML();
