Date from XML

I'm working on a countdown program for a client of mine.

He wants to be able to edit the end date in an xml file, accurate to the second.

I got the timer working fine atm, but i'm kinda struggling with the xml file.
Any of you guys have tips on how i should setup the xml file? and most importantly, how do i extract that same date within the xml file, for use in my program?

Thanks,

Mark

Here's an example I just to build some XML:

Code:

---

Public Shared Function BuildBookInMemory(strRoot As String, strHeader As String, Data As OleDbDataReader) As XmlDocument
        'Create this:
'            <?xml version="1.0"?>
'            <Library>
'              <Book BookType="ExistsInDB">
'                <ID>1</ID>
'                <Author>Joe</Author>
'                <AuthorID>1</AuthorID>
'                <Comment>Excellent</Comment>
'                <CommentID>1</CommentID>
'                <Read>False</Read>
'                <Title>book 1</Title>
'              </Book>
'            </Library>                 
'           

        Dim r As Integer
        Dim xmlBook As XmlDocument
        Dim xmlDec As XmlDeclaration
        Dim xmlRoot As XmlElement
        Dim xmlFirstNode As XmlElement

                "Title"}


        xmlBook = New XmlDocument()
        xmlDec = xmlBook.CreateXmlDeclaration("1.0", Nothing, Nothing)
        xmlBook.AppendChild(xmlDec)
        xmlRoot = xmlBook.CreateElement(strRoot)
        xmlBook.AppendChild(xmlRoot)

        xmlFirstNode = xmlBook.CreateElement(strHeader)
        xmlFirstNode.SetAttribute("BookType", "ExistsInDB")
        xmlRoot.AppendChild(xmlFirstNode)
        For r = 0 To 6
                xmlNode = xmlBook.CreateElement(strNodes(r))
                xmlNode.InnerText = Data(r).ToString()
                xmlFirstNode.AppendChild(xmlNode)
        Next

        Return xmlBook
End Function
