Answer 1

You can use SelectMany for this:

var state = from b in getdata().Descendants("state")
                               .SelectMany(state => state.Elements("text"))
            orderby (string) b
            select (string) b;

In this example, SelectMany selects the "text" elements from each "state" element and flattens them into one sequence.
