I have do
using(System.IO.FileStream fs = System.IO.File.Create("test.xml"))
fs.Write(encodedDefinition, 0, encodedDefinition.Length);
The result is here : http://patxi.mayol.free.fr/test.xml
http://patxi.mayol.free.fr/test.xml
How know that my document have the utf-8 xml preamble ?
About the string "xmlns=\"namespace\"", i have not this in my xml file.
Thanks
