删除xml节点-Xelement [英] Remove xml node -Xelement

问题描述

我有一个xml文件，只需删除特定的节点即可.节点名称将作为用户输入给出.如何删除已向用户请求的特定节点?

I have a xml file from which only specific nodes have to be removed. The node name will be given as input from the user. How to remove the specific nodes which have requested from the user?

<Customers>    
  <Customer>    
    <id>michle</id>
    <address>newjersy</address>    
  </Customer>    
  <Customer>    
    <id>ann</id>
    <address>canada</address>    
  </Customer>
</Customers>

我尝试过

var customer = new XElement("customer",
      from o in customers
      select 
          new XElement("id", id),
          new XElement("address", address)
        );

客户将包含一个新节点

<Customer>    
  <id>ann</id>
  <address>canada</address>    
</Customer>

doc.Element("customers").Elements(customer).ToList().Remove();

但是这不起作用.如何从xml中删除元素?

but this is not working. How can I remove the element from the xml?

推荐答案

Tom，

尝试一下...

private static void RemoveNode(string sID)
    {
        XDocument doc = XDocument.Load(@"D:\\Projects\\RemoveNode.xml");

        var v = from n in doc.Descendants("Customer")
                     where n.Element("id").Value == sID
                     select n;
        v.Remove();
        doc.Save(@"D:\\Projects\\RemoveNode.xml");
    }

当我使用

RemoveNode("michle");

希望这会有所帮助.
