I don't think you need to, see below.

Right, but when you do GetRepoList() you'll have the repo ID's returned,
so in this case you'll get fedora9 rather than fedora.

A URL isn't a useful classifier as some repos will have local mirrors or
just a mirrorlist as the URL.

Se above, the URL is a really bad ID.

Well, I would need to know what you're trying to achieve -- certainly I
don't think you should be enabling repositories for the user unless
there's a very good reason to do so. If the user has a custom repository
config with different names for the repositories than what you are
expecting -- then it's probably best you don't try and guess what the
user wants to do.
