How to convert a TextMate Grammar (XML flavor) to either YAML or JSON flavor

Question

Textmate grammar (.tmLanguage files) are sometimes expressed in XML format.

I would like to convert to a more readable format (i.e. JSON or YAML) to integrate in a VS Code Syntax Highlighting Extension.

To clarify what I mean, here are a few examples:

• XML format
• YAML format (equivalent to the previous one)
• JSON format

I could write a script in Python to do that but it would save me some time if such converter already exists.

Thanks

The TextMate Languages extension has some commands built-in for this. Screenshot from the readme:

Awesome! I wrote a python script anyway, not very complex data structure. – Incline

Press CTRL+SHIFT+P and type Convert to see this view. It works really fast for XML. – Coercive

This extension is now unmaintained, but this fork is up-to-date: marketplace.visualstudio.com/items?itemName=pedro-w.tmlanguage – Filing

Isn't a python library one can use to not depend on this vscode extension? – Shurwood
