HTML::TokeParser::Simple makes this task very simple:

use HTML::TokeParser::Simple;

my $p = HTML::TokeParser::Simple->new(*DATA);

while ( my $token = $p->get_token() ) {
    if ( $token->is_text() ) {
        $token->[1] =~ s/2004/2006/;
    }
    print $token->as_is;
}

__DATA__
<html>
<head>
</head>
<body>
<h1 id="2004">Euro 2004 : The English were robbed</h1>
<p>We <strong>will</strong> have revenge in the 2006 World Cup!</p>

The 2004 occurring as an HTML attribute and the 2004 in the comment remain unchanged.

Used H:T:Simple's nice ->is_text() method

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;
