Question

I’m using DOMDocument to generate a XML and this XML has to have an image-Tag.

Somehow, when I do (simplified)

$response = new DOMDocument();
$actions = $response->createElement('actions');
$response->appendChild($actions);

$imageElement = $response->createElement('image'); 
$actions->appendChild($imageElement);

$anotherNode = $response->createElement('nodexy');
$imageElement->appendChild($anotherNode);

it results in

 <actions>
    <img>
    <node></node>
 </actions>

If I change ‘image’ to ‘images’ or even ‘img’ it works. It does work as well when I switch from PHP 5.3.10 to 5.3.8.

Is this a bug or a feature? My guess is that DOMDocuments assumes that I want to build an HTML img Element … Can I prevent this somehow?

Weird thing on top: I’m not able to reproduce the error in another script on the same server. But I do not catch the pattern …

Here’s a complete pastebin of the class, that’s causing the error: http://pastebin.com/KqidsssM

That costed me two hours.

DOMDocument renders the XML correctly. The XML is returned by an ajax call and somehow the browser/javascript changes it to img before displaying it …
