function your_html_search_and_replace( &$search, &$replace, &$search_regex, &$replace_regex ) {

	# regular string replace
	$search[] = 'string';
	$replace[] = '';

	# regex replace
	$search_regex[] = '|regex (string)|i';
	$replace_regex[] = '$1';

	return $search; // required
}

add_filter( 'abtf_html_replace', 'your_html_search_and_replace', 10, 4 );
