How do I extract the contents of an rpm?

Question

I have an rpm and I want to treat it like a tarball. I want to extract the contents into a directory so I can inspect the contents. I am familiar with the querying commands of an uninstalled package. I do not simply want a list of the contents of the rpm. i.e.

$ rpm -qpl foo.rpm

I want to inspect the contents of several files contained in the rpm. I do not want to install the rpm. I am also aware of the rpms ability to do additional modifictions in the %post sections, and how to check for those. i.e.

$ rpm -qp --scripts foo.rpm

However in this case that is of no concern to me.

In NixOS, there is rpmextract. It is a wrapper around rpm2cpio, exactly as @Alan Evangelista wanted. https://github.com/NixOS/nixpkgs/tree/master/pkgs/tools/archivers/rpmextract
