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

Idea about helper functions is from one of the comments for DOM on php.net and idea about using unset is from kavoir.com. For me this solution finally worked:

function Myunset($node)
{
 unsetChildren($node);
 $parent = $node->parentNode;
 unset($node);
}

function unsetChildren($node)
{
 while (isset($node->firstChild))
 {
 unsetChildren($node->firstChild);
 unset($node->firstChild);
 }
}

using it: $xml is SimpleXmlElement

Myunset($xml->channel->item[$i]);

The result is stored in $xml, so don’t worry about assigning it to any variable.
