If the counterparty provides a price list in YML format from Yandex Market, then columns can be automatically defined for this file format. Categories, products, prices, descriptions, attributes and photos will be loaded from the file. 
Manual configuration of loading data from XML
There are cases when the XML file is not in the Yandex Market YML format or manual configuration is required in order, for example, to load data from the desired tag into the desired program column. This can be an attribute of the product that needs to be loaded, for example, in the "Manufacturer's Article" field.
To do this, you need to turn on the manual mode for setting up the XML file, reopen the window to update the view, and then go to "Column Addresses" to start manual settings.
To upload photos and product attributes, you must specify the product ID from the price list in order to establish a link. To do this, add 2 fields:
- "Product code (string UUID)" and specify the name of the [id] tag
- "Category ID (UUID string)" and specify the name of the categoryId tag
Then add tags to column addresses
To load data from attributes (properties, parameters, characteristics) from a file into the field you need, you must use the following syntax:
param[@name='XXX'], where XXX is the name of the attribute from the file in the specified tag
< param name='Название' > значение<param>< param name='Название' > значение<param>
YML format tags are used to upload photos and attributes. For attributes, this is param, for a photo, picture, you don’t need to write them anywhere, but if there are other names in the price list, you will need to enter them here
After setting up all the required fields for uploading, you need to click the "Upload data" button.
As you can see, category data, photos, descriptions have loaded.
Information about the attributes was loaded into the appropriate section and the article that we took from the attribute ended up in the standard field "Manufacturer's SKU"
