<?php $_items = $this->getReviewsCollection()->getItems();?>
<div class="box-collateral box-reviews" id="customer-reviews">
    <?php if (count($_items)):?>
        <div class="review-heading">

                </table>
                <?php endif; ?>

                    /
                   <?php echo $this->__('(Posted on %s)', $this->formatDate($_review->getCreatedAt()), 'long') ?>
                </span>
            </dd>
        <?php endforeach; ?>
        </dl>

        <?php // echo $this->getChildHtml('toolbar') ?>
    <?php elseif($this->getParentBlock()): ?>
        <?php echo $this->getParentBlock()->getReviewsSummaryHtml($this->getProduct(), 'short', true)?>
    <?php endif;?>
    <?php echo $this->getChildHtml('review_form') ?>
</div>

UPDATE:
this gives the value like

Quality : 2 
Price : 3
Value : 1

But i want to print star.

should i hard code this.

$this->escapeHtml($_vote->getValue())
