XMLTable不从XML中的子级获取数据
我有这段XML数据,需要使用XMLTable获取其bulletinWork:id和bulletinWork/outOfService/outOfService/document:destinationName 有人知道我做错了什么吗? 我需要得到:XMLTable不从XML中的子级获取数据,xml,oracle,plsql,xmltable,Xml,Oracle,Plsql,Xmltable,我有这段XML数据,需要使用XMLTable获取其bulletinWork:id和bulletinWork/outOfService/outOfService/document:destinationName 有人知道我做错了什么吗? 我需要得到: Id DestinationName ------------------------------------- ------------------ 5307cedc

对于不固定的属性,不必使用名称空间。它们的名称空间定义为父元素
在示例xml中有多个cern:outOfService,这就是我使用字符串连接和不同值的原因
更新:
它更长,但对我来说更清晰。两个xml表的联接

你的解决方案很好用,谢谢。我只是稍微调整了一下这个问题,因为为了验证的目的,我可能需要在之后分别使用所有DestinationName。有没有办法让我同时拥有他们而不是加入他们?你的解决方案很好,谢谢。我只是稍微调整了一下这个问题,因为为了验证的目的,我可能需要在之后分别使用所有DestinationName。有没有办法让他们两个都来,而不是加入他们?
