Creating an XML element with a namespace with XmlDocument.CreateElement()

Question

I\'m trying to create an XmlDocument using C# and .NET (version 2.0.. yes, version 2.0). I have set the namespace attributes using:

document.Doc         


        

Answer 1

You can assign a namespace to your bar element by using XmlDocument.CreateElement Method (String, String, String)

Example:

using System;
using System.Xml;

XmlDocument document = new XmlDocument();

// "foo"                    => namespace prefix
// "bar"                    => element local name
// "http://tempuri.org/foo" => namespace URI

XmlElement element = document.CreateElement(
    "foo", "bar", "http://tempuri.org/foo");

document.AppendChild(element);
Console.WriteLine(document.OuterXml);

Expected Output #1:

For a more interesting example, insert these statements before document.AppendChild(element);:

XmlElement childElement1 = document.CreateElement("foo", "bizz",
    "http://tempuri.org/foo");

element.AppendChild(childElement1);
    
XmlElement childElement2 = document.CreateElement("foo", "buzz",
    "http://tempuri.org/foo");

element.AppendChild(childElement2);

Expected Output #2:

Note that the child elements bizz and buzz are prefixed with the namespace prefix foo, and that the namespace URI http://tempuri.org/foo isn't repeated on the child elements since it is defined within the parent element bar.
