php getElementsByTagName with specific attribute

Question

I think this gets the first element called

$gallery = $objDOM->getElementsByTagName(\'gallery\')->item(0);

Answer 1

This is only possible with DOMXPath, e.g.

$xp    = new DOMXPath($yourDOMDocument);
$nodes = $xp->query('//gallery[@name="Third"]');

or by iterating over the node list after the call to getElementsByTagName with

foreach ($objDOM->getElementsByTagName('gallery') as $gallery) {
    if($gallery->getAttribute('name') === 'Third') {
         // do something
    }
}
