Catmandu::AlephX::Response - base class for xml-responses from the AlephX-server
All responses from the AlephX-server share the same functionality and keys: - expressed in XML - name of the parent element is equal to the parameter 'op', except when the value in 'op' is not recognized. Then it is set to 'login'. - when an internal error occurred, the error is reported in the key 'error' - session-id is reported in the key 'session-id' - al the other subkeys are be treated as 'data' All public methods from Catmandu::AlephX return an object of a subclass of Catmandu::AlepX::Response. In case of connection errors, or xml parsing problems, exceptions are thrown.
