VS 2008 Loading XML Data Into Application?

I can successfully save my application data to an .xml structured file like:

<?xml version="1.0"?>
<appSaved>
<saved Firstname="Graham" Lastname="McCann" Email="graham23s@hotmail.com" Username="graham23s" />
</appSaved>

I was trying to do the reverse and load the data back into the textbox fields so far i have:

'Load the saved information back into the textboxes
' Create a new instance of XmlDocument
Dim myXmlDocument As Xml.XmlDocument = New Xml.XmlDocument()

[Code].....
