There is an error in XML document (2, 2).What does this mean?

Question

I am trying to read XML document. My XML:

<?xml version="1.0" encoding="utf-8"?>
<SplashScreen xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <Path>SplashScreen/Image-King</Path>
</SplashScreen>

My code which is reading XML:

XmlGameScreen = new XmlManager<GameScreen>();
XmlGameScreen.Type = currentscreen.Type;
currentscreen = XmlGameScreen.Load("LoadXML/SplashScreen.xml");

And

public Type Type;
public T Load(string path)
{
    T instance;
    using (TextReader textreader = new StreamReader(path))
    {

        XmlSerializer xml = new XmlSerializer(Type);
        instance = (T)xml.Deserialize(textreader);
    }
    return instance; 
}

I am getting error on instance = (T)xml.Deserialize(textreader); Is my XML document wrong? I am trying to read <Path>. Update : My Internal Exception: Cannot serialize member 'MyRPGgame.SplashScreen._image' of type 'Microsoft.Xna.Framework.Graphics.Texture2D'

Solution 1

My experience from it would be that in the 2nd line in the 2nd chararacter, there is an error. have a look if your class names are different from the XML tags. are you maybe changing the "XML Root name" to a different one.

Have a look at the XML structure and which class are you serializing to which node.

Also, read the MSDN Documentation about the XmlRootAttribute Class.

Solution 2

In my case it appears one of the Visual Studio 2017 version 15.5 updates caused this error when trying to open SSRS projects. The solution is to delete the *.rptproj.rsuser file from the project folder and try again.

Solution 3

That usually means you have whitespace at the start of the file; check for a line-break before the <?xml.... Even better: please show the first few bytes (preferably as far as <SplashScreen) of the file as viewed in a binary editor.

It could also mean you have an invisible unicode or control character somewhere before the <SplashScreen

Solution 4

Just wanted to share what worked for me. I had a similar error

System.InvalidOperationException: There is an error in XML document (1, 40). ---> System.InvalidOperationException: <tsResponse xmlns='http://xxxyyyzzzz.com/api'> was not expected.

I was trying to deserialize a string to an object of type tsResponse.

After adding the following attribute [Serializable, XmlRoot(ElementName = "tsResponse", Namespace = "http://xxxyyyzzzz.com/api")] to the class tsResponse i was able to resolve my issue.

[Serializable, XmlRoot(ElementName = "tsResponse", Namespace = "http://xxxyyyzzzz.com/api")]
public class tsResponse
{
    [XmlElement]
    public CredentialsXml credentials { get; set; }
}

I.e had to add Namespace attribute (System.Xml.Serialization).

I think (2, 2) means the error is in line 2, column 2. But the XML document looks OK. Are you sure you aren't loading something else?

[Losser Bad]

No only this xml document...

[Steve Wellens]

Add a line of code (textreader.ReadToEnd()) to put the output of the text reader into a string and use the debugger to examine it. (As a sanity check).

Problem is your instantiating an XmlManager of type GameScreen but trying to load an XML file with type SplashScreen in it. Maybe. I'm not sure because I do not understand the semantic difference between T and Type in your code. Perhaps showing those two extra types would be helpful. This code works for me if SplashScreen is a subclass of GameScreen.

[Losser Bad]

yes SplashScreen is a subclass of GameScreen

Just as a side note to fellow readers in the future: after a while struggling with these issues I decided to switch to JSON. If you a can do so in your project as well and it suits your interests just three words: go for it.

From my experience, this error means that the root element has another Tag name than expected. The actual tag name begins on line 2, character 2.

also try deleting any *.suo files

I delete the .sln file and the project loaded. It looks like there was an encoding error in the sln file.

I didn't have an rsuser file as the project was coming from TFS. So I created a new SSRS project, found the differences in it vs the project I could not open (which were just XML namespaces), changed the project I couldn't open, and then opened that project.

I've tried delete some files as this answer suggest. A workaround which works for me was create a new SSRS project, then add all existent elements.

I deleted both *.rptproj.ruser and *.rptproj.user and this fixed the issue for me. I had the same issue as @user875318, trying to open an SSRS solution in Visual Studio 2017 version 15.5.7.

[Yury Kozlov]

I had the same issue, when I tried to open (by mistake) solution from VS2015 instead of VS2017.

[Don Cheadle]

@YuryKozlov - sounds like in other words, you had a 2017 project, but were trying to open it in VS 2015 and thus an error. That was how I got this error (someone upgraded it from 2015 to 2017 without telling others).
