How to convert symfony yaml config files to xml format?

Question

I\'d like to hold symfony config and routing files as XML files. I know, there are many code examples in the symfony-book but not all configurations-types are shown.

The Symfony2 package (2.4.0) contains yml type files for their AcmeDemoBundle. It is a hassle to change those existing yml files. However, you can make a little modifications that make your newly created bundles use xml format config and routing. You can modify /app/config/config.yml

# resource: "%kernel.root_dir%/config/routing.yml"
resource: "%kernel.root_dir%/config/routing.xml"

Also, /app/config/routing_dev.yml

# resource: routing.yml
resource: routing.xml

By doing these changes, you can choose to use xml when you build your own bundles.
