Template Class:::Help ME

[PlaGuE]

okay i have this template class.

<?php
class Page
{
  var $page;

  function Page($tpl_file = "testy.php") {
  $template = "$tpl_file";
    if (file_exists($template))
      $this->page = join("", file($template));
    else
      die("Template file $template not found.");
  }

  function parse($file) {
    ob_start();
    include($file);
    $buffer = ob_get_contents();
    ob_end_clean();
    return $buffer;
  }

  function replace_tags($tags = array()) {
    if (sizeof($tags) > 0)
      foreach ($tags as $tag => $data) {
        $data = (file_exists($data)) ? $this->parse($data) : $data;
        $this->page = eregi_replace("{" . $tag . "}", $data,
                      $this->page);
        }
    else
      die("No tags designated for replacement.");
  }

  function output() {
    echo $this->page;
  }
}
?>

require_once("lib/parser.php");
$page = new Page("templates/test/index.body.php");

$page->replace_tags(array(
  "title" => "HOME",
  "added_by" => "$row[author]",
  "added_on" => "$row[date]",
"begin_cat_row" => "?????",
"end_cat_row" => "????"
));

$page->output(); 

<table width="100%"  border="0" cellspacing="0" cellpadding="0">
  <tr>
    <th scope="col">Title</th>
    <th scope="col"> Added on</th>
    <th scope="col">Added by</th>
  </tr>
<!--- {begin_cat_row}-->
  <tr>
    <th scope="col">{title}</th>
    <th scope="col">{added_on}</th>
    <th scope="col">{added_by}</th>
  </tr>
<!--- {end_cat_row}-->
</table> 

how. would i be able to 'loop' JUST

<!--- {begin_cat_row}-->
  <tr>
    <th scope="col">{title}</th>
    <th scope="col">{added_on}</th>
    <th scope="col">{added_by}</th>
  </tr>
<!--- {end_cat_row}--> 

This would save a hell of a lot of time .... n skinning and in coding.

Tho if anyone found a better example for this... plz tell me.
