Task
Some YML products have an empty barcode or text instead of a barcode. The import should keep only items with a valid-looking code.
Short answer
Add an export condition to offer: barcode must match regular expression ^(?:[0-9]{8}|[0-9]{12,14})$ (matches a digits-only string with length 8, 12, 13, or 14; it does not validate the check digit).
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
barcode:barcode^(?:[0-9]{8}|[0-9]{12,14})$.
The condition is applied to the whole item.

</yml_catalog>What to keep in mind
- If you only need to remove empty values, use
is not emptywithout a regular expression. - The regular expression checks the format, but not the barcode check digit.
