Add function to delete all source elements at once #335

Open TobiasNx opened 10 months ago

Catmandu has for marc21 a variable record that can be used to remove all elements of the source data. Since record can be a element name, I would suggest a function remove_sourceRecord or something like that to delete all source elements.

Can you provide a link to the documentation?

So it's not a "variable", just a regular field. Metafix doesn't have/need this field, but instead operates on the record itself.

How is your proposed remove_sourceRecord different from remove_field(*) or reject()?

blackwinter commented 10 months ago

Oh, I see, you want to remove the source fields, but keep any newly added fields? Without having to explicitly enumerate them in retain()?

Not sure if this is feasible, but it's certainly a use case.
