Hi,
Well, the google products plugin in HikaShop Business does provide a XML of the products in your shop.
However, the format of the XML corresponds to what Google Merchant wants. Not the format you need. For example, the fields delivery_latvija, delivery_latvijas_pasts, etc do not exist in the XML.
So if you want that exact format, it will require developping a script to generate that XML with the exact format you need.
You could potentially base yourself on the google products plugin, but it will still require to have some PHP developer skills.
