Modules Openerp 6.1 - Invalid XML for view

Question

I'm doing some homework in Python. I need to create a new module for OpenErp 6.1 and I see the next message in a pop up when I try to install the upgrade:

OpenERP Warning
ValidateError
Error ocurred while validating the field(s) arch: Invalid XML for View Architecture!

I attached my developed code.
Could anyone help me please.
