CONVERT XML file encoding with UTF-8 into UTF-16 in c#

Hi Vulpes,

I got solution to convert into utf-16 with dtds.

here is the code:

 var filePath = Application.StartupPath;

              string[] filePaths = Directory.GetFiles(filePath, "*.xml"); // get all the xml files from relative folder

               
                foreach (string xyz in filePaths) // Take each xml file from folder
                {


                    string filepath = xyz;
                    StreamReader fileStream = new StreamReader(filepath);
                    string fileContent = fileStream.ReadToEnd();
                    fileStream.Close();


                    StreamWriter ansiWriter = new StreamWriter(filepath.Replace(".xml", "-unic.xml"), false, Encoding.Unicode);
                    ansiWriter.Write(fileContent);
                    ansiWriter.Close();
}



Thanks for you support

I imagine that these are custom entities defined in the DTD file.

If you can look up what unicode characters they represent, then you'd be better replacing them with those characters in the XML file before you try to load it and do the conversion.

The multiplication sign is character 00d7 hex or 215 decimal.

It's easy to do this programatically and they're a security risk in any case.

Hi,

actually i tried like you(replaced with space) and it s working.

is there any other solution to this problem?

thanks allot

Yeah, the problem is that the utf-8 XML file won't even load because it contains two undefined entities:

&SGV;

×

The second of these is an HTML entity for the multiplication sign but I have no idea what the first one is :-/

Anyway, I removed the first one altogether and replaced the second one with 'x' and it then loaded and converted fine :)

Hi,

it is giving me exception like "Reference to undeclared entity 'SGV'. Line 24, position 95." at the code line var doc = XDocument.Load(utf8FilePath);

hi Vulpes,

go  through attachment.

Hi Vulpes.

here is my xml code.

Jitendra,

You've forgotten to attach the file.

If you just post the declaration section, that should be enough for me to figure out why it's not working.

Hi vulpes,

thanks alot. it is working for some xml files.

I try to load a some other xml files. But it is giving error.

Please go through attachment and u will find my xml document.

If you want to preserve the original file (at least during testing), the code will be something like this:

hi vulpes,

thanks alot.

i have already an xml file on my desktop with utf-8 and i want to change it to utf-16.

could you please write the source code.


jitendra

It should be just a case of loading the utf-8 XML file into memory, changing the declaration's encoding attribute to "utf-16" and then resaving to a new file.

Here's some very simple LINQ to XML code which shows how to do this:
