Yes. Based on the fragment of file that you've given, here's some psuedo-code.
initialise 3 arrays, $top, $middle, $bottom;
$found_middle = 0; $found_bottom;
for each $line in input array {
if ($line not digit) {
if (!$found_middle) {
$top[] = $line; }
else {
$bottom[] = $line;
}}
else {
$found_middle = 1;
$middle[] = $line;
}
}
// Now you have 3 arrays,
// $top contains all lines before the IPs,
// $middle contains lines with IPs,
// $bottom contains all lines after the IPs
Do what you need to edit $middle then write $top, $middle, $bottom out to the
file.
