How to apply a loop in xml report for odoo 8?

The following is the rml report code I used in openerp 7:

<para style="terp_default_2">[[ repeatIn([line for line in picking.move_lines if ((line.state == 'confirmed' or line.state=='done' or line.state=='assigned') and not line.scrapped)],'move_lines') ]]</para>

I need to convert this to odoo 8. How can I apply the same condition in XML report for odoo 8? The following is an example of looping in odoo 8 xml report:

<tr t-foreach="o.order_line" t-as="l">

I need to apply the same condition used in rml for a similar loop.

Thanks And Regards,
