You should really be copying from your XML object into a flatter AS object first - for binding and inline editing and whatnot as the XML objects contain *much* voodoo that can bite you. But here's a quick example using a datagrid rather than a list. As for updating and persisting the XML object, that exercise is left to the reader ;-)
