Validation errors when using NativeXML Plugin for export issues

We recently received a standalone journal based on OJS2.x. We want to move the journal to our production multi-journal installation based on OJS 3.3.0-5. I have managed to upgrade the journal from OJS 2.x to 3.3.0-5.

Am now trying to use the Native XML Plugin under “Export Issues” tab. When I select an issue and click on «Export Issues» button, it produces the following message:

Validation errors:

`Element '{}submission_file', attribute 'stage': [facet 'enumeration'] The value '' is not an element of the set {'public', 'submission', 'note', 'review_file', 'review_attachment', 'final', 'fair_copy', 'editor', 'copyedit', 'proof', 'production_ready', 'attachment', 'query', 'review_revision', 'dependent'}.`


Element '{}submission_file', attribute 'stage': '' is not a valid value of the local atomic type.

Element '{}issue': Missing child element(s). Expected is ( {}articles ).

Is it a problem of invalid XML and how can I validate the XML, etc?

Thanks in advance.


I run into the same problem - is there any known solution to this issue?


We ran into the same problem. You may find a solution here [OJS] Errors when trying to export issues

I assume, this error occurs, when a “file stage” was removed in a newer OJS version. The file stage is saved as a number at every record. There might be old entries with a file stage, which does not exist anymore in the corresponding classes file pkp-lib/ at 6375f0ac97ea4a93381ce8851a6c871a32415583 · pkp/pkp-lib · GitHub after an update of OJS. Therefore the “stage” is now empty, which produces this very XML error.
