Edit specific Element in XDocument

Question

I recently started learning C# and I ran into a problem using `XML.Linq` to store data. I hope the question is understandable as I am not familiar with all the correct terms yet and as English isn't my first language. I read a lot of Questions/googled but I can not figure it out myself. I want to update an existing XDocument File that looks like this: ``` 2 ....... 1 Mr Prename1 Surname1 100 100 2 Mr Prename2 Surname2 100 100 ``` What is the easiest way to change a value in a specific Element? Let's say I want to change the balance of a specific savegame. I want to access the savegame…

Accepted Answer

With `using System.Xml.Linq;` it becomes

```
 var doc = XElement.Load(fileName);
 var saveGame = doc
      .Element("savegames")
      .Elements("savegame")
      .Where(e => e.Element("IdNumber").Value == "2")
      .Single();

saveGame.Element("balance").Value = "50";

doc.Save(fileName);
```
