I want to remove encoding="UTF-8" from the line: <?xml version="1.0" encoding="UTF-8"?> in an xml file using C#.

I have seen fuctions to update other elelments but not this, can anyone please help....

I want to update an existing xml file with element: <?xml version="1.0" encoding="UTF-8"?> to <?xml version="1.0"?>.

Thanks!

The XML declaration is part of the serialized XML, it's not normally represented as part of the in-memory data model that your C# program sees, because "encoding" has no meaning there. Look at the class you use to serialize the XML (e.g an XmlTextWriter) and see if there is a method to set the encoding on the output.

There is a declaration class in C#, code below will do it....

// Load document.
XmlDocument pDoc = new XmlDocument();
pDoc.Load("input.xml");

// Get first node (and check if it is a xml declaration).
XmlDeclaration pDecl = pDoc.FirstChild as XmlDeclaration;
if (pDecl == null)
{
    // No xml declaration exists, create one.
    pDecl = pDoc.CreateXmlDeclaration("1.0", null, null);
    pDoc.InsertBefore(pDecl, pDoc.FirstChild);
}
else
{
    // Modify the one we got.
    pDecl.Encoding = null;
}

// Save document.
pDoc.Save("output.xml");
