Technote Details :: I get a developer error when importing an XML file
Issue
When I start the import from an XML file, I get an error message saying:
Column colname is missing from the XML file. Import aborted. (XML_IMPORT_COLUMN_ERROR).
Reason
This happens because one of the columns marked as requested in the XML Import Wizard was not found in the XML file. This means that the XML file does not comply with the accepted format.
Solution
To check what the XML file should contain, simply check the sample displayed below the file selection form.

Compare it against the XML structure of the file you tried to import and find the missing column. Then either use a different file, or manually add the column.
