Can we generate Pivot reports in Odoo with the data in XML format without storing it in database?

We have data in XML file currently. We need to show this data as pivot report in odoo. 

So, If any ready made apps available to read data in XML and show it as pivot report in odoo (without storing it in database), it will be helpful.

please share the link if anyone knows about it.

Thanks
