The Dockerfile uses the Schematron skeleton to build an XSLT 2.0 file from an input Schematron file.

The Docker container runs an Apache web server listening on port 80, hosting a set of PHP endpoints that validate an input XML file against the appropriate JATS DTD, format the XML, and/or validate the XML against the Schematron rules using SaxonProcessor.

1. Build the Docker image:

docker build . --platform linux/amd64 --tag jats-validator

1. Start the Docker container:

docker run --rm --publish 4000:80 --name jats-validator jats-validator

1. Open http://localhost:4000/ and choose a JATS XML file to validate.

The web service is deployed to Cloud Run via GitHub Actions when the main branch updates.
