XML: Why can't I create a parent node for my document?

I'm trying to write an XML file. The first thing I want to do is create the
parent node for the document:

eleMenuItems = xmldoc.CreateElement("menuItems")
xmldoc.DocumentElement.PrependChild(eleMenuItems)

The second line above causes by try statement to exit and catches this
generic error:

'Object reference not set to an instance of an object'

I'm not sure where to do now to figure out the problem. Is there something I
am missing concept wise when creating the parent node?

You need to insert it as the document element before you dereference the document element - i.e.

XmlNode n = d.CreateElement("Foo");
d.InsertAfter(n, null);

Thanks, Richard.

In the end, I scrapped this method and went with an XMLWriter one. Which I
got working.

Which raises the question, when should I use XMLWriters and when should I
use XMLDoc?
