SSE SSEEdit Scripting: How to copy all records of a certain type into a new plugin, where they will be modified?

[Tranquilitas]

I am trying to create a patcher for certain records in SSEEdit. It is supposed to:

• Check if a record is of a certain type (works)
• Copy that record (or if there are multiple in different files, copy the conflict winner) into a new file created by the patcher (need help)
• (Do i also have to add the files i copied from as masters?)
• After copying the records, modify only the records in the new file (need help)

This would allow me not to modify the existing records, meaning it is unintrusive like other patchers. Help would be greatly appreciated.
