如果需要从多个级别（每个级别都有多个节点）获取数据，可以使用多个XMLTable构造：
select x1.employee_id, x1.position_id,
to_date(x2.start_date, 'YYYY-MM-DD-HH24:MI') as start_date,
x2.order_1, x2.fund_id
from xml_table t
cross join xmltable (
xmlnamespaces ('http://schemas.xmlsoap.org/soap/envelope/' AS "env",
'urn:com.workday/bsvc' as "wd"),
'/env:Envelope/env:Body/wd:Get_Worker_Costing_Allocations_Response/wd:Response_Data/wd:Worker_Costing_Allocations_Data'
passing t.raw_xml
columns Employee_ID number path 'wd:Worker_Reference/wd:ID[@wd:type="Employee_ID"]',
Position_ID varchar2(100) path 'wd:Position_Reference/wd:ID[@wd:type="Position_ID"]',
Interval_Data xmltype path 'wd:Worker_Costing_Allocation_Interval_Data'
) x1
cross join xmltable (
xmlnamespaces ('urn:com.workday/bsvc' as "wd"),
'/wd:Worker_Costing_Allocation_Interval_Data/wd:Worker_Costing_Allocation_Detail_Data'
passing x1.Interval_Data
columns start_Date varchar2(16) path './../wd:Start_Date',

第一个XMLTable获取员工和职位ID，以及它自己的XMLType，即Worker\u Costing\u Allocation\u Interval\u Data
片段。第二个XMLTable被传递给该片段，并在该级别提取多个值。如果需要的话，你可以降低更多的级别
请注意，某些节点的特定实例的过滤器已更改；例如，我没有使用[2]
获取第二个工作者参考ID，而是使用[@wd:type=“Employee\u ID”]
等查找特定属性值，并对基金ID使用类似的构造；您的原始代码正在查找名为Fund\u ID
的属性，而不是具有该类型值的属性
您可以在一个级别中执行此操作，但是树后面的引用可以得到一点帮助
select x.employee_id, x.position_id,
to_date(x.start_date, 'YYYY-MM-DD-HH24:MI') as start_date,
