XElement.SetElementValue overwrites elements

Question

I've the following structure:

<Root name="jack">
     <Ele1>4</Ele1>
     <Ele2>4</Ele2>
     <Ele3>4</Ele3>
     <Ele4>4</Ele4>
</Root>

I want to modify some values so I use the following code:

XElement root1 = new XElement("Root");
root1.SetAttributeValue("name", "jack");
root1.SetElementValue("Ele1", 1);
root1.SetElementValue("Ele2", 2);
root1.SetElementValue("Ele3", 3);

The result of this is a new structure:

<Root name="jack">
     <Ele3>3</Ele3>
</Root>

If I print root1 Debug.Log(root1)after setting the value of Ele2 the result is:

<Root name="jack">
     <Ele2>2</Ele2>
</Root>

Respectively if I do after setting the value of Ele1.

I'm using C# & MonoDevelop for Unity3D.

Answer 1

It seems to be a problem with Unity3D because it's a very simple code. Like I said, the structure is there, so I can read first instead of modify it directly. What I've done after read root1 from the xml file:

string name;
foreach ( XElement ele in root1.Elements() ){
    name = ele.Name.LocalName;
    if ( !doNotChange.Contains (name) )
        ele.SetValue ( PlayerPrefs.GetInt( name ) );
}
        

Where doNotChange is a List of strings that contains those elements who I dont need to modify. I don't really know why SetElementValue does not work in Unity3D but SetValue does. I've reported it to Unity3D. I'll edit the post with their answer.
