在 c# 中重新排列 Xml 子节点

Question

我在重新排列 xml 数据时遇到问题。

我有这样的

<PolicySummary>
    <InsuredName></InsuredName>
    <PolicyNumber></PolicyNumber>
    <PrevPolicyNumber></PrevPolicyNumber>
    <PolicyState></PolicyState>
    <TotalPremium></TotalPremium>
    <Address></Address>
    <Address1></Address1>
    <City></City>
    <State></State>
    <Zip></Zip>
</PolicySummary>

但我想要这样

 <PolicySummary>
     <InsuredName></InsuredName>
     <PolicyNumber></PolicyNumber>
     <PrevPolicyNumber></PrevPolicyNumber>
     <PolicyState></PolicyState>
     <TotalPremium></TotalPremium>
     <MailingAddress>
         <Address></Address>
         <Address1></Address1>
         <City></City>
         <State></State>
         <Zip></Zip>
     </MailingAddress>
</PolicySummary>

我希望邮寄地址节点应该包含地址，地址1，城市，州，邮政编码，任何人都可以提供帮助。我尝试了很多方法，例如附加子级，之后插入但没有任何效果

我试图获取节点并插入邮寄地址并附加它

XmlDocument policysummary = new XmlDocument();
XmlNode copynode = policysummary.ImportNode(
   xmlautoDocument.SelectSingleNode("PolicySummary/TotalPremium"), true);
XmlNode premium = policysummary.SelectSingleNode("TotalPremium");
XmlNode addressss = policysummary.CreateNode(XmlNodeType.Element,
                                            "Mailingaddress", null);
XmlNode root2 = policysummary.DocumentElement;
premium.InsertAfter(addressss, premium);

使用 XDocument 而不是 XmlDocument 尝试此操作：

var xDoc = XDocument.Parse(xmlString)
var root = xDoc.Element("PolicySummary");
var totalPremium = root.Element("TotalPremium");
//get all values you want to put in mailing address
var address = root.Element("Address");
//...
var mailingAddress = new XElement("MailingAddress");
mailingAddress.Add(address);
//Add mailing address after total premium
totalPremium.AddAfterSelf(mailingAddress);
//Remove all values you inserted in mailing address
address.Remove();
//If you want to save it somewhere
xDoc.Save(fileName);
