How to integrate XML with Zoho CRM

How to integrate XML with Zoho CRM

Hi,
I have an eCom service provider that gives me a dynamic XML that contains order information, clients, shipments...

The XML link is the only thing I have. No Oath or key, No API get...

I want to integrate it into Zoho CRM.
I am not a developer nor knowing code.

Is there any simple way to do it?
