I needed something like that once and ended up with this:
sub UA {
my $ua = shift;
my $n = "";
my $v = "";
# $n is the name of the browser
# $v the version
$ $p the platform
# $ua the full useragent string
# grap the beginning of the UA string for the name
($n) = ($ua =~ m/^([^\/]+)\//);
# but everything calls itself Mozilla, so let's check for a few more
# known browsers
$n = "msie" if m/MSIE/;
# it's worse, these babies calls themself both MSIE and Mozilla, doh!
$n = "webtv" if m/webtv/i;
$n = "opera" if m/opera/i;
# try getting the version
($v) = ($ua =~ m/\/((\d+)(\.\d+)?)/)[0];
# loosen up what we match on a little and try again if we didn't get
# a match
($v) = ($ua =~ m/((\d+)(\.\d+)?)/)[0] unless $v;
# these thingies call themself Mozilla/N.Z, so let's get their real
# version number
($v) = (m/MSIE ((\d+)(\.\d+)?)/) if ($n eq "msie");
($v) = (m/webtv\/((\d+)(\.\d+)?)/i) if ($n eq "webtv");
($v) = (m/opera[\s\/]((\d+)(\.\d+)?)/i) if ($n eq "opera");
# guess the platform
my $p = "";
$p = "w" if $ua =~ m/win/i;
$p = "w16" if $ua =~ m/win(dows)?\s?3\.1/i;
$p = "w16" if $ua =~ m/win.*16(bit)?/i;
$p = "w95" if $ua =~ m/win(dows)?\s?95/i;
$p = "w98" if $ua =~ m/win(dows)?\s?98/i;
$p = "wnt" if $ua =~ m/win(dows)?\s?NT/i;
$p = "w32" if $ua =~ m/win(dows)?\s?32/i;
$p = "x11" if $ua =~ m/X11/;
$p = "mac" if $ua =~ m/mac/i;
$p = "os2" if $ua =~ m/os\/2/i;
$p = "webtv" if $n eq "webtv";
$n = lc($n);
die "No name for $ua?\n" unless $n;
#return $n, $v, $p;
return "$n-$v-$p";
}
