Auth_Yadis_Service::Auth_Yadis_Service

(

)

Creates an empty service object.

        $this->element = null;
        $this->parser = null;
    }

Auth_Yadis_Service::getElements

(

$name

)

Used to get XML elements from this object's <Service> element.

This is what you should use to get all custom information out of this element. This is used by service filter functions to determine whether a service element contains specific tags, etc. NOTE: this only considers elements which are direct children of the <Service> element for this object.

Parameters

string

$name

The name of the element to look for

Returns

array $list An array of elements with the specified name which are direct children of the <Service> element. The nodes returned by this function can be passed to $this->parser methods (see Auth_Yadis_XMLParser).
