i working ganon dom parser html parsing , trying content div block reason returned object not working, below code , using : 

<?php set_time_limit(0); #include dom parser lib. require_once('ganon.php');  $html = file_get_dom('http://jlc.watchprosite.com/?show=forumpost&amp;fi=2&amp;pi=1818820&amp;ti=279373&amp;msid=&amp;s='); print_r($html("div[id='sidebar']")->childcount());  ?>
