如何从XML中删除列表父节点？

Question

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：-

<scheme-master>
    <general-information>

        <year>2020</year>

Answer 1

您正在循环访问XDocument的XElement Element根节点，但尝试从文档本身删除 节点。而是从当前的元素中删除它们：

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。
