wget -qO- http://ftp.altlinux.org/pub/distributions/ALTLinux/Sisyphus/aarch64/base/srclist.classic.xz | unxz > srclist.classic
pkglist-query '%{name}-%{version}-%{release}.%{arch}.rpm\n' pkglist.classic
pkglist-query '%{name}-%{version}-%{release}.src.rpm\n' srclist.classic

The source for pkglist-query utility follows, it should build against any librpm version available (thanks at@, legion@, glebfm@):
