Returns the parent DomNode object for this DomNode object.


  RETURNS xml.DomNode


This method returns the parent xml.DomNode object for this DomNode object, or NULL. In the case of a xml.DomDocument node, this method will return NULL (parent is not a DomNode object) but isAttached() will return TRUE.

In case of error, the method throws an exception and sets the status variable. Depending on the error, a human-readable description of the problem is available in the sqlca.sqlerrm register. See Error handling in GWS calls (status).
