我是 XML 数据库的新手，在为 transportEquipment 的 id 写入 where 条件时遇到问题。

我的xml是：

下面是从数据库中获取的 xml。这个xml在transportequipment中有多个id，我们需要在id上写where条件。我能够在 localreferencenumber 和标识符等上写 where 条件。但是没有写在transportEquipment的“id”上，bcz这里有很多。

<?xml version = '1.0' encoding = 'UTF-8' standalone = 'yes'?>

并且我无法将 where 条件添加到以下查询

select * from (select x.id "id",x.creationTime "creationTime",x.localReferenceNumber "localReferenceNumber",x.customsStatus "customsStatus",x.messageSent "messageSent",x.messageSuccess "messageSuccess",x.processStep "processStep",x.lastReceivedRelevantMessage "lastReceivedRelevantMessage",x.isFallBackDeclaration "isFallBackDeclaration",x.declarationType "declarationType" from dmsimport_decl,xmltable(xmlnamespaces('http://www.minihouse.eu/myunidoc/schema/common' as "c",default 'http://www.minihouse.eu/myunidoc/dms/schema/dmsimport','http://www.minihouse.eu/myunidoc/dms/schema/dmsimport' as "d"),'/declaration' passing object_value columns id number(19) path 'c:declarationHeader/c:identifier/text()',creationTime timestamp path 'c:declarationHeader/c:creationTime/text()',localReferenceNumber varchar2(35 char) path 'c:declarationHeader/c:localReferenceNumber/text()',customsStatus varchar2(3) path 'c:declarationHeader/c:status/c:customsStatus/text()',messageSent number(1) path 'c:declarationHeader/c:status/c:messageSent/text()',messageSuccess number(1) path 'c:declarationHeader/c:status/c:messageSuccess/text()',processStep number(4) path 'c:declarationHeader/c:status/c:processStep/text()',lastReceivedRelevantMessage number(4) path 'c:declarationHeader/c:status/c:lastReceivedRelevantMessage/text()',isFallBackDeclaration number(1) path 'c:declarationHeader/c:status/c:isFallBackDeclaration/text()',declarationType varchar2(1) path 'declarationTypeCode/declarationType/text()',username varchar2(81) path 'c:declarationHeader/c:username/text()') x where   lower(localReferenceNumber) = 'nldms1234567890001234' order by creationTime desc,x.localReferenceNumber desc ) where rownum <= 1000

以下查询将有所帮助

SELECT * FROM XXXtabelXXX XMLTable(
XMLNAMESPACES(  DEFAULT 'http://www.minihouse.eu/myunidoc/dms/schema/dmsimport',
'http://www.minihouse.eu/myunidoc/schema/common' AS "c"),
'/declaration' PASSING d.object_value COLUMNS
  lrn VARCHAR2(35 CHAR) PATH 'c:declarationHeader/c:localReferenceNumber/text()',
  declarationId VARCHAR2(35 CHAR) PATH 'c:declarationHeader/c:identifier/text()',
  transport xmlType PATH 'goodsShipments/consignment/transportEquipment') xmlDataAlias,
  XMLTable (XMLNAMESPACES( DEFAULT 'http://www.minihouse.eu/myunidoc/dms/schema/dmsimport'),
  'transportEquipment' passing transport COLUMNS
  id VARCHAR2(4 CHAR) PATH 'id' ) transportInfo
 WHERE transportInfo.id = 'abcd'
