If you are going to read the whole file into memory you also allow for the following solution which seems more simple and direct than working with splice.

use strict;
use warnings;

my $file_content = do {
    local $/ = undef;
    <DATA>;
};

$file_content =~ s/
    (?:.*\n)?
    ^X{5}.*\n
    (?:.*\n)?//xmg;

print $file_content;

__DATA__
XXXXX
Aoooo
XXXXX is my name
Boooo
11111
22222
33333
Coooo
XXXXX is what I play
Doooo

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:
