You need to do some searching on how XML is done on .NET. I will need many pages to explain it all. But since we added XML support to FEZ it make sense now to add examples to the free ebook.

Here is a simple example to make a simple XML file. You need to change the memory stream with file stream to write to a file…or take the buffer at the end and write it to a file.

public static void Main()
{

System.IO.MemoryStream ms = new System.IO.MemoryStream();

System.Ext.Xml.XmlWriter xmlwrite = System.Ext.Xml.XmlWriter.Create(ms);

xmlwrite.WriteComment("This is an XML example file");
xmlwrite.WriteProcessingInstruction("xml", "version='1.0', encoding='UTF-8'");

xmlwrite.WriteStartElement("Device");
xmlwrite.WriteString("FEZ");
xmlwrite.WriteEndElement();

xmlwrite.WriteStartElement("Type");
xmlwrite.WriteString("Domino");
xmlwrite.WriteEndElement();

xmlwrite.Flush();
xmlwrite.Close();

byte[] bb = ms.ToArray();
//char[] cc = System.Text.UTF8Encoding.UTF8.GetChars(bb);
char[] cc = System.Text.Encoding.UTF8.GetChars(bb);
string str = new string(cc);
Debug.Print(str);

}

Hi,

Thanks for the quick response. I am new to programming and just wrote my first application that uses xml recently. I used the assembly System.XML in my application.

In your sample it appears you are using an assembly with the name System.Ext.XML. I am having trouble locating that assembly.

Like I said before, you need to do some searching. If you did search and can’t find an answer then we are here ready to help :slight_smile:

Let me google that for you, so I search google for “System.Ext.Xml” :smiley:

And this is the first hit
http://www.eggheadcafe.com/software/aspnet/35331897/where-is-xmltextwriter-an.aspx

Which shows that it is in the MFDpwsExtensions assembly.
