We don’t have a tutorial like that. Generating XML is pretty complicated and typically requires some programming experience.
There isn’t any prefabricated script that will transform a csv file into valid Crossref xml. We experimented with building one some years ago, but it just produced too much data loss.
That said, we know there are members who have written their own scripts to convert csv to xml. The reason those can work is that the members know exactly how they organize their own metadata in csv format, and more importantly, they only use a single content type, and a very minimal subset of all possible metadata elements. The schema is too complicated for a ‘one size fits all approach’, but it can work if you’re only supply the bare minimum metadata.
But in general, help with creating xml is beyond the scope of what we can offer.
If there are other members on the forum who have had experience successfully writing a csv-to-xml conversion for their own use, or otherwise picking up xml skills, we’d love to hear their input!
