如果存在多个节点，查询将不起作用。

将名称空间添加到查询中：

;使用XMLNAMESPACES（'http://www.abc.zy/kudos/kentucy“作为ns1）
挑选
客户价值（‘（ns1:ImporterNr）[1]，‘nvarchar（50）’）作为‘ImporterNr’，
客户价值（“（ns1:ForwarderNr）[1]”，将“nVarchar（50）”作为“ForwarderNr”，
客户值（'（ns1:Items/ns1:Item/ns1:AddressType）[1]，'nVarchar（50）'作为'AddressType'
从…起
@XML.nodes（'/ns1:Dealer/ns1:Head'）作为AOC（Cust）

或者将其从XML中删除。

非常感谢。我只想知道如果存在多个节点，该怎么办。ie@explore365请更新您的问题，或创建一个新问题
