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. Fast option: add an export condition on
barcode-Is not emptyif you only need to remove products without a barcode.
This option checks that a value exists, but does not check the barcode format. Strict option: add an export condition on
barcode-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).
This option removes empty values and text such as bad-code.
