Xml root element attributes

[Mikus Sleiners]

I want to create xml document that looks like this:

<?xml version="1.0" encoding="utf-16"?>

As you can see there are 3 attributes on the root level. I am trying to set
these attributes this way:

XmlDocument xml = new XmlDocument();

XmlDeclaration declaration = xml.CreateXmlDeclaration ("1.0",
"utf-16", null);

xml.AppendChild(declaration);

//Root element
XmlElement elemDraft = xml.CreateElement
("Draft");//,"http://www.w3.org/2001/XMLSchema");

//Root element attributes
XmlAttribute attr1 = xml.CreateAttribute ("xmlns:xsi");
attr1.Value = "http://www.w3.org/2001/XMLSchema-instance";
elemDraft.Attributes.Append (attr1);

XmlAttribute attr2 = xml.CreateAttribute ("xmlns:xsd");
attr2.Value = "http://www.w3.org/2001/XMLSchema";
elemDraft.Attributes.Append (attr2);

XmlAttribute attr3 = xml.CreateAttribute ("xsi:type");
attr3.Value = "TravelDraft";
elemDraft.Attributes.Append (attr3);

xml.AppendChild (elemDraft);

when this is done i get following xml document

<?xml version="1.0" encoding="utf-16"?>
<Draft xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema" type="TravelDraft">
</Draft>

Notice that everything is just like i wanted except for last attribute -
type. It should look like xsi:type="TravelDraft", but xsi prefix is absent.
Why is that ?

I want to create xml document that looks like this:

<?xml version="1.0" encoding="utf-16"?>
<Draft xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema" xsi:type="TravelDraft">

Here is one way:

const string xmlnsURI = @"http://www.w3.org/2000/xmlns/";

XmlDocument xmlDocument = new XmlDocument();

xmlDocument.AppendChild(xmlDocument.CreateXmlDeclaration("1.0",
"UTF-16", null));

xmlDocument.AppendChild(xmlDocument.CreateElement("Draft"));

XmlAttribute xmlnsXsi = xmlDocument.CreateAttribute("xmlns",
"xsi", xmlnsURI);
xmlnsXsi.Value = XmlSchema.InstanceNamespace;
xmlDocument.DocumentElement.SetAttributeNode(xmlnsXsi);

XmlAttribute xmlnsXsd = xmlDocument.CreateAttribute("xmlns",
"xsd", xmlnsURI);
xmlnsXsd.Value = XmlSchema.Namespace;
xmlDocument.DocumentElement.SetAttributeNode(xmlnsXsd);

XmlAttribute xsiType = xmlDocument.CreateAttribute("xsi", "type",
XmlSchema.InstanceNamespace);
xsiType.Value = "TravelDraft";
xmlDocument.DocumentElement.SetAttributeNode(xsiType);

You need
using System.Xml;
using System.Xml.Schema;
for that code.

Thanks Martin.

Here is one way:

XmlDocument xmlDocument = new XmlDocument();

xmlDocument.AppendChild(xmlDocument.CreateXmlDeclaration("1.0",
"UTF-16", null));

xmlDocument.AppendChild(xmlDocument.CreateElement("Draft"));

XmlAttribute xmlnsXsi = xmlDocument.CreateAttribute("xmlns", "xsi",
xmlnsURI);
xmlnsXsi.Value = XmlSchema.InstanceNamespace;
xmlDocument.DocumentElement.SetAttributeNode(xmlnsXsi);

XmlAttribute xmlnsXsd = xmlDocument.CreateAttribute("xmlns", "xsd",
xmlnsURI);
xmlnsXsd.Value = XmlSchema.Namespace;
xmlDocument.DocumentElement.SetAttributeNode(xmlnsXsd);

XmlAttribute xsiType = xmlDocument.CreateAttribute("xsi", "type",
XmlSchema.InstanceNamespace);
xsiType.Value = "TravelDraft";
xmlDocument.DocumentElement.SetAttributeNode(xsiType);
