XML is not the only alternative - please don't use it as a straw man. 
For example, here is a fragment from the Bacula docs using their 
hierarchical format:

    FileSet {
       Name = Test
       Include {
         File = /home/xxx/test
         Options {
            regex = ".*\.c$"
         }
       }
    }


Or here is a piece from the buildfarm client config (which is in fact 
perl, but could also be JSON or similar fairly easily):

    mail_events =>
    {
         all => [],
         fail => [],
         change => ['foo@bar.com', 'baz@blurfl.org' ],
         green => [],
    },
    build_env =>
    {
         CCACHE_DIR => "/home/andrew/pgfarmbuild/ccache/$branch",
    },
