Why does parsing return one element?

Question

Parsing

I'm parsing a site using simple html dom .
I use it, for some reason only one found element is returned, the first one:

$html = read($link);
foreach($html->find('a.img') as $val)
{
  pr($val->attr['href']);
}
function read($url){
......................................
  return str_get_html($result);
}

As I understood, find should return an array of all found elements...
