Re: Pimp My RegEx

I get better performance with this:

my $parse_log_entry = qr/^$dateRegex/ms;
...
my $prevpos = 0;
while( $logfile =~ m/$parse_log_entry/g ) {
    $count++;                   # count number of parsed strings
    if ($prevpos) {
#        print "Do something with $prevpos .. $-[0]\n";
#        print substr($logfile, $prevpos, $-[0]-$prevpos), "\n";
    }
    $prevpos = $-[0];
}

You would use the substr expression above to access what you're currently capturing, though you don't indicate that what you're capturing is actually used at all. .

I made a grossly simplified version of my script to share with the forum. Posting the script in its entirety would have just bored folks to tears! ...but rest assured, I am doing something with the captured text. I'm not sure your solution will work for log entries that span multiple lines.	[reply]
