Task
The supplier sent one shared YML feed, but the import needs only two vendors: Acme Lighting and Northline.
Short answer
Add an export condition to offer: vendor must match ^(Acme Lighting|Northline)$ (matches a value that is exactly Acme Lighting or Northline).
How to do it in Eofferix
In the XML/YML snapshot, select the repeated
offernode.Open the node settings.

The animation shows opening settings for the repeated product node. Add an export condition for
vendor:vendor^(Acme Lighting|Northline)$.
The condition is applied to the whole item.

- If only one vendor is needed, use the
equalscondition without a regular expression. - Place the condition on
offerso the whole item is excluded.
