Using LINQ to XML; Information from form to xml and back

This is the form: http://ift.tt/1m6WooR

From this I want to generate an xml like:

<Customers>
    <Customer CustomerID="1">
      <CustomerFirstName>John</CustomerFirstName>
      <CustomerLastName>Smith</CustomerLastName>
      <ContactNumber>0327929387</ContactNumber>
      <Email>stackoverflow@gmail.com</Email>
      <FullAddress>
        <Address>2732 Baker Blvd.</Address>
        <City>Eugene</City>
        <Region>OR</Region>
        <PostalCode>97403</PostalCode>
        <Country>USA</Country>
      </FullAddress>
    </Customer>
</Customers>

and from that be able to read it back into the form and edit the info.
