[ []] [-- ]\n```\n\nFor example, you can transform an ALTO XML to a hOCR file with:\n\n```sh\nocr-transform alto hocr sample.xml sample.hocr\n```\n\nOr convert from ALTO XML (version 2.1) to hOCR with:\n\n```sh\nocr-transform alto2.1 hocr sample.alto sample.hocr\n```\n\nYou can also pass arguments directly to the Saxon CLI by passing them after a double dash (`--`). For example, to set the `foo` parameter to `bar`:\n\n```sh\nocr-transform alto hocr sample.xml sample.hocr -- foo=bar\n```\n\nTry `ocr-transform -h` to get an overview:\n\n\n
