How do I edit Node Values in an existing XML file with C#-CodePudding

I am trying to change the values in a Farming simulator 22 savegame xml file from C# in visual studio. There are a lot of nodes so I have reduced them to make things easier. I want to know how to replace the value in the node using C# with out having to create and rebuild the xml file from scratch.

the path to the xml file is: (C:\Users\Name\Documents\My Games\FarmingSimulator2022\savegame1\careerSavegame.xml)

<?xml version="1.0" encoding="utf-8" standalone="no"?>
<careerSavegame revision="2" valid="true">
  <settings>
    <savegameName>My game save</savegameName>
    <creationDate>2022-05-03</creationDate>
    <mapId>MapFR</mapId>
    <mapTitle>Haut-Beyleron</mapTitle>
    <saveDateFormatted>2022-08-22</saveDateFormatted>
    <saveDate>2022-08-22</saveDate>
    <resetVehicles>false</resetVehicles>
</careerSavegame>

You can use the System.Xml.Linq namespace to access the xml file. This will load the file in the memory.

There is one class inside it, XDocument, that represents the xml document.

String filePath = "C:\Users\Name\Documents\My Games\FarmingSimulator2022\savegame1\careerSavegame.xml"
XDocument xdoc = XDocument.Load(filePath);
var element = xdoc.Elements("MyXmlElement").Single();
element.Value = "foo";
xdoc.Save("file.xml");

You can set the element variable as per the one which is needed to be replaced.

Through some research I found the solution to editing the values within the nodes. In this example I only change the value of savegameName, but it will be the same for the rest.

    //Routing the xml file 
    XmlDocument xmlsettings = new XmlDocument();
    xmlsettings.Load(@"D:\careerSavegame.xml");

    //Setting values to nodes through innertext
    String FarmNameSetting = "Martek Farm";
    XmlNode savegameNamenode = 
    xmlsettings.SelectSingleNode
    ("careerSavegame/settings/savegameName");
    savegameNamenode.InnerText = FarmNameSetting;
