I think that the previous reply is probably the simplest way of doing what you want, and in my opinion the simple is the best.
However I leave you another suggestion that shall work even if your problematic lines don't occur exactly in the first and second lines. (For example if sometimes you have the 2 headers and other you have only one, or if some other thing gets written before or between the 2 headers)
open (my $fh,"<",$file) or die "Can't open file $file: $!";
while (my $line = <$fh>) {
if($line !~ m/^Processor.*/){ #process only lines which not the on
+es starting with "Processor"
#(...)
}
}
