I know it's not the fasionable way to do this, but I just like doing
this sort of thing on the command line with shell tools.
Let's say the command to get the lines out of the file is:
grep '\.rpm$' logfile
(If it's not that, amend as needed.)
Try something like this to get the raw list:
$ grep '\.rpm$' logfile | sed 's/\-[0-9].*//' | fmt -1000
Canna-devel GConf-devel Guppi-devel HelixPlayer Maelstrom MagicPoint
NetworkManager NetworkManager-gnome
$
And something like this to actually install it:
$ rpm -i `grep '\.rpm$' logfile | sed 's/\-[0-9].*//' | fmt -1000`
(Or whatever the `rpm` command is -- I mainly use Debian, not RedHat, so
I forget how to use RPM these days...).

Yeah, you can; the `sed` command above should point you the right way.

Sure, but why seven?
$ echo MagicPoint-1.11b-1.i386.rpm
MagicPoint-1.11b-1.i386.rpm
$ echo MagicPoint-1.11b-1.i386.rpm | sed 's/.*\(.......rpm\)/\1/'
1.i386.rpm
Or some variant on that...
