Javascript script that converts ADL files (Archetype Definition Language) into json objects

I need a script that is able to convert Archetype Definition Language (adl files) into JSON objects. If you need more info into what an adl file is you can look into the following website: https://specifications.openehr.org/releases/AM/latest/ADL1.4.html or you can find files like this in the following repository: https://github.com/gestaopedidosehr/CKM-mirror/tree/master/local/archetypes/cluster.
What I'm paying for is the script to convert these type of files into json object format so gonna need the file you made for this.
