查询在SQL Server中删除XML中的一个标签。

Question

我有一个xml，名字空间如下。我如何删除标签 <ns1:replyTo> 使用XML查询从XML中删除标签。我们可以用下面的查询来删除标签。我不知道如何通过标签与 SOAP-ENV

update tablename 
set XMLColumnname.modify(('delete /ServiceIn/file/sender/replyTo[1]'))

XML。

你当前的XQuery路径是匿名的，而且还从错误的根开始。

你需要定义所需的命名空间，使用的是 with xmlnamespaces 或在XQuery语句本身内部声明命名空间，例如。

create table tablename (
  XMLColumnname xml
);

insert tablename values
(N'<?xml version="1.0"?>

            <ns1:execute
                xmlns:ns1="urn:com.company.us.abc.service.xyz.someService">
                <si:ServiceRequestInfo>
                    <si:Tag1 />
                    <si:Tag2 />

            </ns1:execute>
        </SOAP-ENV:Body>
    </SOAP-ENV:Envelope>');

update tablename    
set XMLColumnname.modify('declare namespace soap="http://schemas.xmlsoap.org/soap/envelope/";
declare namespace foo="urn:com.company.us.abc.service.xyz.someService";
delete /soap:Envelope/soap:Body/foo:execute/foo:ServiceIn/foo:File/foo:Sender/foo:replyTo[1]');

select * from tablename;

Which yields...
