Also look at the TreeDataProvider API, especially getData(), getProperty().
Note that while your data is xml, Flex is changing it into an object. If you want to work with true xml nodes in your tree, set resultFormat="xml" on the HTTPService tag.
You can still use the data provider api, or you can use the xml class properties and methods.
