#write(input_filespec, json_mode: :pretty, json_filespec: nil) ⇒ Object

Public entry point to write JSON file(s) from XML. To write a single file, pass the filespec as the ‘input_filespecs` parameter. To write multiple files, pass an array of filespecs as the `input_filespecs` parameter json_mode: :pretty for human readable JSON, :compact for compact JSON Default json_filespec will be constructed from the input file, just replacing ’xml’ with ‘json’.
