Task
The YML contains normal SKUs and free text in vendorCode. The import needs only codes such as LA-22001.
Short answer
Add an export condition to offer: vendorCode must match regular expression ^[A-Z]{2}-[0-9]{5}$ (matches two uppercase Latin letters, a dash, and five digits from start to end).
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. Method 1: regular expression
^[A-Z]{2}-[0-9]{5}$matches two uppercase Latin letters, a dash, and five digits from start to end.
This is one condition variant; the other variants do not need to be added. Method 2: if a prefix is enough, use
vendorCodeContains substringLA-.
This is one condition variant; the other variants do not need to be added. Method 3: for a stricter prefix check, use
vendorCodeStarts withLA-.
This is one condition variant; the other variants do not need to be added.
