Re: [Libguestfs] [PATCH v3 04/10] lib/osinfo.c: Extract xml processing into a callback

In order to further reuse the osinfo database parsing in OCAML, this commit extracts the XML processing for the distro ISOs and places it into a newly created callback. This will later help other code to traverse the osinfo DB files and let them extract what they need from them.
