I am trying to convert a SXW file into a RML file, using openerp_sxw2rml.py, but it is giving too errors and it is generating an empty RML file. I am sure that the content of the SXW is right, because I am using existing SXW files from the modules, to check if they are being transformed in a right way.

I copied the account_balance.sxw from the account module, and pasted it into openerp_sxw2rml folder to test it. Then I executed this:

sudo ./openerp_sxw2rml.py /opt/openerp7/addons/base_report_designer/openerp_sxw2rml/account_balance.sxw > /opt/openerp7/addons/base_report_designer/openerp_sxw2rml/account_balance.rml

And the result is the next:

./openerp_sxw2rml.py: 30: ./openerp_sxw2rml.py:

Why is this happening? Has anybody had the same problem?

Any help would be appreciated.
