<videos> 
    <category title="Animations"> 
    <video> 
    <videoPath value="video.mp4"/> 
    <previewImage value="image.jpg"/> 
    <aspectRatio value="4:3"/> 
    <totalTime value=""/> 
    <watermarkPath value="http://mydomain.com"/> 
    <watermarkLink value="http://mydomain.com"/> 
    </video> 
    </category> 
</videos> 

在此代碼

我想改變用PHP動態以下

<videoPath value="video.mp4"/> 
    <previewImage value="image.jpg"/> 

或讓我知道我可以用PHP生成整個代碼或包含在PHP

Answer 1

使用DomDocument是一個選項：

$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也可能適合。
