XML insertBefore

[norbi35]

Hello. I'm a newby to php and can't figure out how to apply 'insertBefore' method in my case:

 

XML file:

<gallery>

<image imagePath="galleries/gallery_1/images/1.jpg" thumbPath="galleries/gallery_1/thumbs/1.jpg"> </image>

 

<image imagePath="galleries/gallery_1/images/2.jpg" thumbPath="galleries/gallery_1/thumbs/2.jpg"> </image>

 

<image imagePath="galleries/gallery_1/images/3.jpg" thumbPath="galleries/gallery_1/thumbs/3.jpg"> </image>

 

</gallery>

 

 

 

 

PHP file:

 

$xml = new DOMDocument();

$xml->load('list.xml');

       

$image = $xml->createElement('image');

$image->setAttribute('imagePath','galleries/gallery_1/images/MyImage.jpg');

$image->setAttribute('thumbPath','galleries/gallery_1/thumbs/MyThumb.jpg');

       

echo "<xmp>NEW:\n". $xml->saveXML() ."</xmp>";

 

 

I would like to insert the new $image  before the existing tag <image> that has index = 2;

 

Thanks in advance for any advice.

 

Regards
