Re^2: parsing a bibliography

[tachyon]

One small but worthwhile modification would be to open an errors file and ouput non matching records to it. You could then tune or post process these.

open ERRS, ">error.log" or die $!;
while( ... ) {
    my ( ... ) =~ m/ ... /x;
    if ( $authors ) {
        # output as desired
    }
    else {
        print ERRS "$_\n";
    }
}
close  ERRS;
