Answer 1

Your best bet here may be to use the tSchemaComplianceCheck component in Talend.

If you read the file in with a tFileInputDelimited component and then check it with the tSchemaComplianceCheck where you set cty_cd to not nullable then it will reject your Antarctica row simply for the null where you expect no nulls.

From here you can use a tMap and simply map the fields to the one above.

You should be able to easily tweak this as necessary, potentially with further tSchemaComplianceChecks down the reject lines and mapping to suit. This method is a lot more self explanatory and you don't have to deal with complicated regex's that need complicated management when you want to accommodate different variations of your file structure with the benefit that you will always capture all of the well formatted rows.
