The LINQ to XML object model does not store whether an element parsed is marked up as <foo/> or <foo /> so when saving back such information is lost. If you want to ensure a certain format then you could extend an XmlWriter implementation and override its http://msdn.microsoft.com/en-us/library/system.xml.xmlwriter.writeendelement.aspx but that way you would also not preserve the input format, rather you would then write out any empty elements as <foo/> or whatever format you implement in your method.

There are other changes that can happen, for instance when loading the file
```
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:xhtml="http://www.w3.org/1999/xhtml">
  <head>
    <title>Example</title>
  </head>
  <body>
    <h1>Example</h1>
  </body>
</html>
```
and saving it back the result is
```
<xhtml:html xmlns="http://www.w3.org/1999/xhtml" xmlns:xhtml="http://www.w3.org/1999/xhtml">
  <xhtml:head>
    <xhtml:title>Example</xhtml:title>
  </xhtml:head>
  <xhtml:body>
    <xhtml:h1>Example</xhtml:h1>
  </xhtml:body>
</xhtml:html>
```
so don't expect markup details to be preserved when loading/saving with XDocument/XElement.

To avoid the declaration in the header of the document you can use the following

    XmlWriterSettings settings = new XmlWriterSettings();
    settings.OmitXmlDeclaration = true;


        using (XmlWriter xw = XmlWriter.Create(fileName, settings))
        {
            doc.Save(xw);
        }
