DOMXPath::__construct — Creates a new DOMXPath object
Creates a new DOMXPath object.
The DOMDocument associated with the DOMXPath.
As of PHP 5.2.0, DOMXPath object implements XPath 1.0.
The DOMXPath object doesn't create a reference to the document. If you load a new xml using either load, loadXML or loadHTML functions the DOMXPath object will still query and evaluate over the source in the DOMDocument when it was created.
