I have about 190,000 HTML-files. Every one of those contains some HTML code in the end that I want to get rid of. How can I do that? I tried to solve this problem myself, but none of the solutions I came up with worked. No warnings, no errors, just no effect. For example 
use warnings;
use strict;
use File::Slurp;
local $/ = undef;

for ($i=1; $i < 119000; $i++)
{&s1;}

sub s1 {
open (fl, "+<", "C\:\\convs\\conv$i\.txt");
binmode fl;
$string = <fl>;
$string =~s/^.*Mina olen.{1561}//s;
close(fl);
}

What have I done wrong?

In reply to Removing a chunk of HTML? by Anonymous Monk

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
    ] &#93;
