not working
<div class="col-5 offset-1" name="company_address">
i want if o._name is puchase.order than class should be col-6 and in other cases class should be as it is i.e. col-5 offset-1

i do not want to add t-if in company_address
i check if the model is purchase.order (in qweb report) than i want to add class col-5 in company_address

<xpath expr="//div[@name='company_address']" position="attributes">
<attribute name="class">col-5" t-if="o and o._name == 'purchase.order'"</attribute>
</xpath>

<div class="col-5 offset-1" name="company_address">
i want if o._name is puchase.order than class should be col-6 and in other cases class should be as it is i.e. col-5 offset-1
not working since in both cases same class applied
