XElement.Save Method (Stream, SaveOptions)
Assembly: System.Xml.Linq (in System.Xml.Linq.dll)
By default the options are set to None. This option will remove all extraneous insignificant white space, and add appropriate insignificant white space so that the XML is properly indented.
If you want to save unindented XML, specify the DisableFormatting flag for options. This will cause the writer to write all white spaces exactly as represented in the XML tree.
Use OmitDuplicateNamespaces option if you want to remove duplicate namespace declarations.
