getxml（）返回null结果

Question

dim dsXml as new DataSet
dsXml = someMethodthatReturnDatasetValue

dim sXml as string
sXml = dsXml.getXml().toString

返回结果类似于

<NewDataSet>
<Table>
<IID>8858</IID>
<IsActive>true</IsActive>
<Remark>g</Remark>
</Table>
</NewDataSet>

我的预期结果是返回如下所示。但我的实际结果不会返回对，我该怎么做才能返回名称对，即使我的值为空？

<NewDataSet>
<Table>
<IID>8858</IID>
<Name></Name>
<IsActive>true</IsActive>
<Remark>g</Remark>
</Table>
</NewDataSet>
