c#欲在wpf 隐藏cs文件中点击按钮时自动在xaml文件中添加永久控件，采用类似xml的Dom树操作添加节点，执行后控件属性中多出一个xlms=""，不知道怎么删除

Question

xaml文件中仅仅定义了两个Button（未贴出），下面是xaml.cs文件中点击事件
private void Button_Click(object sender, RoutedEventArgs e)
{
XmlDocument document = new XmlDocument();
document.Load(@"D:\360Learncs\c#\WpfTest\MainWindow.xaml");
XmlNode gridNode= document.DocumentElement.FirstChild;
XmlElement newButton = document.CreateElement("Button");
newButton.SetAttribute("Content", "button3");
newButton.SetAttribute("Margin","40,125,0,0");
gridNode.AppendChild(newButton);
document.Save(@"D:\360Learncs\c#\WpfTest\MainWindow.xaml");
}
