DataList - Saving the data?

I'm displaying data in a DataList control like so:

VB Code:

ds.ReadXml(Server.MapPath("family.xml"))
        DataList1.DataSource = ds
        DataList1.DataBind()

After editing the contents of the textboxes, how should I be saving this?

Try this Mendhak : http://www.aspnet101.com/aspnet101/aspnetcode.aspx

His examples are nice and straightforward for mere mortals like us.

You're pretty resourceful for a Jimi Hendrix fan. :)
