XDocument: saving XML to file without BOM

Question

I\'m generating an utf-8 XML file using XDocument.

XDocument xml_document = new XDocument(
                    new XDeclaration(\"1.0\"         


        

Answer 1

The most expedient way to get rid of the BOM character when using XDocument is to just save the document, then do a straight File read as a file, then write it back out. The File routines will strip the character out for you:

        XDocument xTasks = new XDocument();
        XElement xRoot = new XElement("tasklist",
            new XAttribute("timestamp",lastUpdated),
            new XElement("lasttask",lastTask)
        );
        ...
        xTasks.Add(xRoot);
        xTasks.Save("tasks.xml");

        // read it straight in, write it straight back out. Done.
        string[] lines = File.ReadAllLines("tasks.xml");
        File.WriteAllLines("tasks.xml",lines);

(it's hoky, but it works for the sake of expediency - at least you'll have a well-formed file to upload to your online provider) ;)
