This may seem like a really basic question, but how do I remove a node from an XML document? I know the name and position of the node (its at the top of the document and is a single node meaning it doesn't have a cloding tag).

I tried a few things, but I was only guessing about which methods/properties to use. Can anyone tell me how to do this the right way?

Here is the XML:
Code:
<?xml version="1.0" encoding="UTF-16"?>
<PropertyBag>
	<frmMain>
		<FormMain.WindowState>0</FormMain.WindowState>
		<FormMain.Top>2610</FormMain.Top>
		<FormMain.Left>2985</FormMain.Left>
		<FormMain.Height>6300</FormMain.Height>
		<FormMain.Width>9390</FormMain.Width>
		<Toolbars.Menus>True</Toolbars.Menus>
	</frmMain>
</PropertyBag>
... and I need to remove this line "<?xml version="1.0" encoding="UTF-16"?>"

Any help would be appriciated.
