我有这样的XML数据
<Export>
<Customer>
<Data>
<First_name>ABC</First_name>
<Last_name>DEF</Last_name>
<Addresses>
<Address>
<Country>A</Country>
<City>B</City>
<Street>C</Street>
</Address>
<Address>
<Country>AA</Country>
<City>BB</City>
<Street>CC</Street>
</Address>
</Addresses>
</Data>
<Data>
...
</Data>
</Customer>
</Export>
并希望使用xml类型的sql属性获取这样的XML
<Data>
<First_name>ABC</First_name>
<Last_name>DEF</Last_name>
<Address>
<Country>A</Country>
<City>B</City>
<Street>C</Street>
</Address>
<Address>
<Country>AA</Country>
<City>BB</City>
<Street>CC</Street>
</Address>
</Data>
<Data>
...
</Data>
我使用sql * .modify('delete ...)删除根节点,但无法删除没有嵌套节点的地址节点((((((
