                        <LoginID>123456</LoginID>
                        <Status>SUCCESS</Status>
                    </GetLoginIDResult>
                </GetLoginIDResponse>
            </diffgr:diffgram>
        </GetLoginResult>
    </GetLoginResponse>
</soap:Body>
</soap:Envelope>

我怎样才能分别获得LoginID 和Status？它只在列中显示LoginID 和Status。怎么拆分？

唯一的麻烦是要处理多个命名空间。您可以尝试以下解决方案。

SQL
