Hi!
I’m trying to submit the XML file on DOAJ, but the following message is shown:
“File could not be validated against a known schema; please fix this before attempting to upload again”
When I check the XML file against the XSD on “XML Schema” it appears the message:
“S4s-elt-character: Non-whitespace Characters Are Not Allowed In Schema Elements Other Than ‘xs:appinfo’ And ‘xs:documentation’. Saw ‘XML Schema’.”
How can I fix it?
The XML file exported by OJS system is in the link below:
