The line break shouldn't be necessary. If you have validation turned on, perhaps that is causing some sort of problem. Also check other parsing options.

I just ran last night's bulk whois through xmllint with the --stream option and it worked fine. xmllint uses libxml.

Sorry I can be of further help here.
