On selline XML-i struktuur ning sooviks PHP DOM-i abil muuta kindla testimonial(id järgi) elemendi active vaartust. Mul on kood kustutamaks kindlat elementi, aga ei oska modida muutmiseks.

<?php
$xmlFile = file_get_contents('test.xml');
$xml = new SimpleXMLElement($xmlFile);

$kust_id = $_GET["id"];

foreach($xml->testimonial as $story) {
    if($story['id'] == $kust_id) {
        $dom=dom_import_simplexml($story);
        $dom->parentNode->removeChild($dom);

        $xml->asXML('test.xml');
        header("Location: newfile.php");
    }
}
?>

Ilmselt siis DOMNode::replaceChild

$newelement = $xml>createTextNode('Some new node!'); 
$element->parentNode->replaceChild($newelement, $element); // $element = $dom sinu puhul

Pärineb siinsetest kommentaaridest.

    <?php
// $testimonials = simplexml_load_file('test.xml');
$testimonials = new SimpleXMLElement('<testimonials>
    <testimonial id="4c050652f0c3e">
        <nimi>John</nimi>
        <email>test@test.com</email>
        <text>Some text</text>
        <active>1</active>
        </testimonial>
    <testimonial id="4c05085e1cd4f">
        <name>ats</name>
        <email>some@test.ee</email>
        <text>Great site!</text>
        <active>0</active>
    </testimonial>
</testimonials>');

// there can be only one item with a specific id, but foreach doesn't hurt here
foreach( $testimonials->xpath("testimonial[@id='4c05085e1cd4f']") as $t ) {
  $t->name = 'LALALA';
}

echo $testimonials->asXML();

Kuidas muuta PHP abil XML-i kindlat väärtust ning salvestada fail
