O:) Also, does libvirt produce such files? I don't think we should bother doing extra work to undo the extra work done by the user.Of course, we don't generate XML declarations, but I can imagine tools formatting DOM into a file could just automatically output the XML declaration unless you explicitly tell them not to do so. On the other hand, nothing would output a doctype or <?xml-stylesheet ?> without an explicit action. Moreover, libvirt itself doesn't mind XML declarations and virsh before 4.4.0 didn't mind either. I agree, it's probably a corner case and I was thinking about not fixing it, but it turned out to be really easy thanks to the strict XML specification.>https://bugzilla.redhat.com/show_bug.cgi?id=1595993 I only see a relation between the bug summary and this patch. There's no mention of the XML declaration there and no mention of the other issues mentioned there here in the patch.Oops, the patch is supposed to fix another bug https://bugzilla.redhat.com/show_bug.cgi?id=1592737
