Unfortunately, it can't. Example RPM output:

bzip2-libs-1.0.2-8
glib-1.2.10-10
losetup-2.11y-9
shadow-utils-4.0.3-6
MAKEDEV-3.3.2-5
hotplug-2002_04_01-17
findutils-4.1.7-9
modutils-2.4.22-8
sed-4.0.5-1
...


As you see, pkgnames can contain hyphens, which are also used to 
separate out the version from the pkgname. I suppose you could assume 
that any -[\d] sequence was the beginning of the version, but nothing 
stops someone having a pakgename of 'something-3d' for example. *sigh*.

RPM's format print output options are the only way I can see to do it - 
as well as the way with the least messing about.

Hyphens should probably have been forbidden in pkgnames, but it's a bit 
late now...
