Yeah...I'd say you got your facts mixed up. substr() is very fast, but
also very limited. Regex is slower, but much more flexible.
>From your example:
This is slower, but it will find anything between two braces:
$data_line =~ />([^\<]+)\</;
$tag = $1;
This is faster, but only if you know EXACTLY where to find the piece
you want. One character off and it's useless.
$tag = substr( $data_line, 19, -5 );
