Thanks for the reply.. i want to edit a hikashop code
the code is
<div id="hikashop_product_description_main" class="hikashop_product_description_main" itemprop="description">
<?php
echo JHTML::_('content.prepare',preg_replace('#<hr *id="system-readmore" */>#i','',$this->element->product_description));
