try perl:
#!/usr/bin/perl
while(<>) {
@line = split(/::/);
if $line[0] is something {
do something with $line[2];
}
}
just redirect the file to this script
No guarantees! :)

Yes. for example:
#!/usr/bin/perl
open (FILE,"filename");
@the_whole_file = <FILE>;
foreach(@the_whole_file) {
$line = $_;
blah blah...
}
