The form xbook is a very simple xbook which displays all the types of input tags that can be used to gather values from the user and then echoes the values back to the user. The form which the user will see is in the file index.html. The script which will handle it is in the file script.py. The script defines a class called FormExample which is a subclass of xbooks.activity.handler.HTML. It overloads only 2 routines: initialize and doSubmit. initialize just reads the index.html file and returns it to the out stream. It should be removed from the example when the handler script is fixed (see Section 5.1.1.1). The doSubmit routine searches for each xbook variable that was defined index.html and echoes the value(s) back to out.
