You're going to have to be a bit more clear in your specs. Let's say that we find the letters "fo" at the top of the document and about 200 K later, we find the letter "o". Do you want the substitution then? Kind of tough to tell. What about if you run into a word that contains the target letters, such as "fools"? Just wrapping "foo" in tags is easy (untested code follows). The following uses HTML::TokeParser::Simple instead of HTML::Parser.

use HTML::TokeParser::Simple;
my $p = HTML::TokeParser::Simple->new( \$original_html );

my $new_html = '';
while ( my $token = $p->get_token ) {
    unless ($token->is_text) {
        $new_html .= $token->return_text;
    }
    else {
        my $text = $token->return_text;
        $text =~ s/foo/<bar>foo</bar>/g;
        $new_html .= $text;
    }
}
