Analyze response by looking for error, category and message with the provided XPATH queries

xpath queries must be prefixed with the namespace self::XMLNS_PREFIX

@param SendResult $response
@param string $qErr XPATH query for fetching error code (first node is used)
@param string $qCat XPATH query for fetching error category (first node is used)
@param string $qMsg XPATH query for fetching error messages (all nodes are used)
@param string|null $errLevel Optional custom error level string.
@return Result
