How to delete a element by tag name with all elements inside it

Question

I want to use the dom removeChild function in php to remove everything between a tag.

my xml looks like

  text         


        

Answer 1

$dom = new DOMDocument;
$dom->loadXML($xml);
$dom->getElementsByTagName('root')->item(0)
   ->removeChild($dom->getElementsByTagName('remove')->item(0));

This is very specific, though. You can use XPath if you need more generality:

foreach ($xpath->query('//remove') as $node) {
   $node->parentNode->removeChild($node);
}
