С учетом XML-файла-записи вот так

Я бы хотел получить значения дочерних элементов datum
.
Итак, я написал следующий запрос:
for $i in collection("/db/_DEMO/ADR-NSBG/sipTransactTM/2011/06/09")
let $TIME_FROM := "2011-06-09T00:15:00"
let $TIME_TO := "2011-06-09T00:45:00"
let $DATUM := "SGC_at_bsNo-13___SignalingNetworkConnection_at_netId-4___Sip_at_networkRole-2"
where ( $i/ADR-NSBG/timeline/@timestamp/string(.) >= $TIME_FROM and
$i/ADR-NSBG/timeline/@timestamp/string(.) <= $TIME_TO) and
( $i/ADR-NSBG/timeline/datum/@datum/string(.) = $DATUM )
order by $i/ADR-NSBG/timeline/@timestamp/string(.)
return $i/ADR-NSBG/timeline/datum
Но проблема в том, что я не могу выбирать между двумя "базовыми" узлами.
Результат запроса:
<datum datum="SGC_at_bsNo-14___SignalingNetworkConnection_at_netId-4___Sip_at_networkRole-2">
<sbgSipTotalIncSipRequests>4314320</sbgSipTotalIncSipRequests>

Я хотел бы спросить вас: почему утверждение ( $i/ADR-NSBG/timeline/datum/@datum/string(.) = $DATUM )
не работает?
