我尝试使用下面的代码从XML下面删除scheme-details1，但无法删除。
XmlActionResult xmlActionResult = new XmlActionResult(schememaster);
foreach (XElement element in xmlActionResult._document.Elements())
{
xmlActionResult._document.Elements("scheme-details1").Remove();
}
其中XMLActionResult._Document是XDocument。
以下是我的XML响应：-

您正在循环访问XDocument的XElement Element根节点，但尝试从文档本身删除元素中删除它们：
foreach (var element in xmlActionResult._document.Elements())
{
//xmlActionResult._document.Elements("scheme-details1").Remove(); // FIXED
element.Elements("scheme-details1").Remove();
}
或者，由于格式良好的XML文档总是只有一个根元素，您可以省去根元素的循环，只需执行以下操作：
xmlActionResult._document.Root.Elements("scheme-details1").Remove();
这里是演示。
