Question

Answer 1

If you extend the base SimpleXMLElement class, you can use this method:

class MyXML extends SimpleXMLElement {

    public function find($xpath) {
        $tmp = $this->xpath($xpath);
        return isset($tmp[0])? $tmp[0]: null;
    }

    public function remove() {
        $dom = dom_import_simplexml($this);
        return $dom->parentNode->removeChild($dom);
    }

}

// Example: removing the  element with id = 1
$foo = new MyXML('');
$foo->find('//bar[@id="1"]')->remove();
print $foo->asXML(); //
