Frankly, the easiest approach is to bite the bullet and go for a
regexp approach. Digging out a bit of old Perl code that did this
job (if for slightly differently formatted log lines):

while (<STDIN>) {
    /^([0-9.]+) ([^ ]) ([^ ]) (\[.+\]) \"([^\"]+)\" ([0-9]+) ([0-9]+) \"([^\"]+)\" \"([^\"]+)\"/;

    $hitter = $1;
    $datestr = $4;
    $httpcmd = $5;
    $httpres = $6;
    $size = $7;
    $referer = $8;
    $agentid = $9;

}
