Write or append the Element to XML file using XmlDocument

[yxq]

I want to add some elements to a XML file using XmlDocument, how to do?
thank you very much.
The original XML file like:
////////////////////////////////////////////////////////
<?xml version="1.0" encoding="utf-8" ?>
<AAA>
<BBB>
<CCC>
<resource name="111">Content1</resource>
<resource name="222">Content2</resource>
</CCC>
</BBB>
</AAA>
///////////////////////////////////////////////////////

After added elements(the "DDD" elements), it sould like:
////////////////////////////////////////////////////
<?xml version="1.0" encoding="utf-8" ?>
<AAA>
<BBB>
<CCC>
<resource name="111">Content1</resource>
<resource name="222">Content2</resource>
</CCC>

<DDD>
<resource name="333">Content3</resource>
<resource name="444">Content4</resource>
</DDD>

</BBB>
</AAA>
////////////////////////////////////////////////////

Load the original XML document into a System.Xml.XmlDocument, create and
insert the new elements and save the XmlDocument back e.g.

Dim doc As New XmlDocument()
doc.Load("..\..\XMLFile1.xml")

Dim ddd As XmlElement = doc.CreateElement("DDD")

Dim resource As XmlElement = doc.CreateElement("resource")
resource.SetAttribute("name", "333")
resource.InnerText = "Content3"
ddd.AppendChild(resource)

resource = doc.CreateElement("resource")
resource.SetAttribute("name", "444")
resource.InnerText = "Content4"
ddd.AppendChild(resource)

doc.DocumentElement("BBB").AppendChild(ddd)

'Save to Console for testing, could of course save to file
doc.Save(Console.Out)
