Question

我在ASP.NET 4.0中遇到DataSet.GetXml（）问题：
首先，我用一些表格填充数据集然后我在数据集上运行.GetXml（）方法，并返回一些XML。但是，这种方法的输出不希望我想要它。

期望的结果是：

简而言之，我也在数据集的表中获取了空白的单元格，并且这些单元格的xml节点获得了xml：space =“preserve”。我如何阻止这种情况发生？我的意思是，如何阻止细胞被包括在内？

在ASP.NET 1.1中使用相同的代码并返回所需的输出。这意味着我可能需要打开/关闭4.0中的新功能。但是什么？

非常感谢任何帮助。

提前致谢：）

我从未发现如何正确地执行此操作，因此现在我只应用RegEx删除任何具有xml：space =“preserve”属性的空标记：

Dim reSpaceReplacer As New Regex("<[^ ]+ xml:space=""preserve"">\s+</[^>]+>")
strOutput = reSpaceReplacer.Replace(strOutput, "")

DataSet.GetXml（）将空表单元格转换为具有属性xml的标记：space =“preserve”和值空间
