在XML中添加元素和节点

Question

我有一个接收以下XML的应用程序，我必须添加一些额外的信息（新元素）。你能帮我理解怎么做吗？

<Feed>
  <Claims>
    <Claim>
      <ClaimID>123</ClaimID>
      <Reference>245</Reference>
      <AccidentDetails>
        <IncidentDate>2015-08-05</IncidentDate>
      </AccidentDetails>
      <DriverDetails>
        <DriverFirstName>Text</DriverFirstName>
        <DriverLastName>Text</DriverLastName>
      </DriverDetails>
      <ClientVehicleDetails>
        <VehicleLegallyDriveable>Yes</VehicleLegallyDriveable>
        <VehicleLocation>In Use</VehicleLocation>
      </ClientVehicleDetails>
    </Claim>
  </Claims>
</Feed>

但我需要加载XML并添加如下所示的部分

<Feed>
  //This is the section I need to add to my XML
  <Control>
    <Username>Test</Username>
    <Password>TestPass</Password>
  </Control>
  //The following XML will remain the same
  <Claims>
    <Claim>
      <ClaimID>123</ClaimID>
      <Reference>245</Reference>
      <AccidentDetails>
        <IncidentDate>2015-08-05</IncidentDate>
      </AccidentDetails>
      <DriverDetails>
        <DriverFirstName>Text</DriverFirstName>
        <DriverLastName>Text</DriverLastName>
      </DriverDetails>
      <ClientVehicleDetails>
        <VehicleLegallyDriveable>Yes</VehicleLegallyDriveable>
        <VehicleLocation>In Use</VehicleLocation>
      </ClientVehicleDetails>
    </Claim>
  </Claims>
</Feed>

您可以使用LINQ-to-XML轻松完成此操作： -

XDocument xdoc = XDocument.Load("ClaimXMLFile");
XDocument xdoc2 = new XDocument(new XElement("Feed",
                                  new XElement("Control",
                                      new XElement("Username", "TestPass"),
                                      new XElement("Password", "Test")),
                                            xdoc.Root));
xdoc2.Save(@"NewXMLFileName");
