Answer 1

Using DomDocument is one option:

$dom = new DomDocument;
$dom->loadXml($xml);
$videoPaths = $dom->getElementsByTagName('videoPath');
foreach ($videoPaths as $videoPath) {
  $videoPath->setAttribute('value', 'newvideo.mp4');
}
$previewImages = $dom->getElementsByTagName('previewImage');
foreach ($previewImages as $previewImage) {
  $previewImage->setAttribute('value', 'newimage.jpg');
}
$xml = $dom->saveXml();

SimpleXML may also suit.
