Hello all I installed the odoo on my local machine on Windows 7. Then I open the command line as adminsistrator and

cd C:\Program Files (x86)\Odoo 8.0-20150123\server\openerp\addons\base_report_designer\openerp_sxw2rml.

Then I execute, 

python openerp_sxw2rml.py a.sxw > a.rml

I got this error,

File "openerp_sxw2rml.py", if self.styles_dom.getElementsByTagName("style:page-master").__len__()<>0:
