there's some support in the git master for irrtoolset
(https://github.com/irrtoolset/irrtoolset) for XR config in rtconfig.
It's been tested by at least one person.

If your main use case is handling prefix lists, you would be much better
off using BGPQ3.  This tool is far superior to irrtoolset for handling
prefix lists and will output to json which means that you can import the
data directly into any scripting language you like rather than having to
deal with the limited syntax supported by rtconfig.
