get xml from database and convert it to array- Zend Framework

I am using the Zend Framework ,I want to convert XML to array and show them in view

Here is my code:

Controller:

  public function reportAction(){

    $reportModel = new Model_Report();
    $select_report = $reportModel->fetchAll($reportModel->select()->where( "phone = '888' )->order('date DESC'));
    $rowCount = count($select_report);
    $test = $select_report->toArray();
    print_r($test[0]['message'])  ;
    if ($rowCount > 0) {
        $this->view->rowCount = count($select_report);
        $this->view->rowArray = $select_report->toArray();   
    } 
}

View :

<table>
     <tr>
        <th>voice</th>
        <th>quality</th>
        <th>network connection</th>
      </tr>
    <?php 
                for ($i=0 ; $i<$this->rowCount; ++$i)
                {
                        print  '<td>'. ($this->rowArray[$i]['message']).'</td>';
                }?>
</table>

My XML in message like this :

<root><voice>false</voice><quality>false</quality><network>true</network></root>

I want to show XML's value in table in View. but it just show : falsefalsetrue
