What you want to do is deserialize your data from the XML into a
sequence of dicts for the grid. Then when time to save the XML, you
serialize your data back into XML. I think ElementTree is a sane way to go.
Again, what the grid wants would be something like:
grid.DataSet = [{"boo": True, str1: "hello", str2: "there"},
{"boo": False, str1: "star", str2: "wars"},
{"boo": False, str1: "comedy", str2: "drama"}]
So a sequence of dicts, where each dict has the same keys. Each dict
represents a record, and each key/value pair represents a field. In the
example above, your grid would show three records.
