TSQL删除XML节点（如果其子元素包含给定值）

Question

XML存储在<Addresses>下可以有零个或多个<Address>节点需要查询以删除任何<Address> <AddressLine> = '2 Church Lane' <Address>节点

启动XML：

declare @t table (storage xml);
insert into @t (storage)
select '<Person>
  <Fullname />
  <Surname>Smith</Surname>
  <FirstName>John</FirstName>
  <Addresses>
      <Address>
        <AddressLine>1 Church Lane</AddressLine>
      </Address>
      <Address>
        <AddressLine>2 Church Lane</AddressLine>
      </Address>
      <Address>
        <AddressLine>3 Church Lane</AddressLine>
      </Address>
  </Addresses>
</Person>';

产生的XML：

<Person>
  <Fullname />
  <Surname>Smith</Surname>
  <FirstName>John</FirstName>
  <Addresses>
      <Address>
        <AddressLine>1 Church Lane</AddressLine>
      </Address>
      <Address>
        <AddressLine>3 Church Lane</AddressLine>
      </Address>
  </Addresses>
</Person>
