Regular Expression Help

Hiya,

I am having issues trying to get figure out a regular expression to grab the alt attribute of an img tag.. Here is what I have so far but cant seem to actually get it to work.

          $regexp = "/<img|<image*alt=(\"|'??)([^\"|' >]*?)*\/>|>/siU";
          if (preg_match($regexp, $this->anchortext[$i], $matches)) {
                $this->anchortext[$i] = $matches[3];
          }

PHP:

Any ideas?

Thanks
