Remove a child with a specific attribute, in SimpleXML for PHP

Question

I have several identical elements with different attributes that I\'m accessing with SimpleXML:

Answer 1

Just unset the node:

$str = <<
  
    
    
  

STR;

$xml = simplexml_load_string($str);
unset($xml –> a –> b –> c); // this would remove node c
echo $xml –> asXML(); // xml document string without node c

This code was taken from How to delete / remove nodes in SimpleXML.
