Hello my friends,
please have patience with me. I'm a bloody perl-beginner :)

My problem:
I have a big file and inside there is an html-file hidden.

My quest:
I want to extract only this html-file from the big file. So I guess I have to search the big file for strings like "<html>" and "</html>".

So far:
I did a little test with a png-file. Here is my code:

#!/usr/bin/env perl
use strict;
use warnings;

open(INPUT, "<test_in.png") or die $!;
open(OUTPUT, ">test_out.png") or die $!;

while(<INPUT>)
   {
   last if /END/;        
   print OUTPUT $_;
   };

close INPUT;
close OUTPUT;

Weird result:
Inside every png-file there is an "END" string pretty much at the end. But this code doesn't output the data from beginning to that word "END". It ends a few bits before. The same code with a text-file where I put the word "END" inbetween works.

I hope you can clear the clouds in my brain...

Sincerely,
Ni
