In this example, we modify the XML document from the previous example to use a namespace prefix `contact` for the `http://example.com/contact` namespace. We use the `contact:type` syntax to specify the attribute name in `getAttributeNS`.
Package/library: The DOMElement getAttributeNS method is part of the core PHP DOM extension, which is included with PHP by default. No additional package or library is needed to use this method. /**

public function getBalance()
{
return $this->element->getAttributeNs('http://www.xbrl.org/2003/instance', 'balance');
}
