Regex pattern for preg_match_all

Hi folks, This is not directly relating to PHP but it's Friday so I'm gonna give it a shot :). Would someone please help me figure out why my regex pattern doesn't work. Below is the code and sample data: $html = <<<HTML <li class="small tab "><a class="y-mast-link images" href="http://images.search.yahoo.com/images" data-b="http://www.yahoo.com"><span class="tab-cover y-mast-bg-hide" style="padding-left:0em;padding-right:0em;">Images</span></a></li> <li class="small tab "><a class="y-mast-link video" href="http://video.search.yahoo.com/video" data-b="http://www.yahoo.com"><span class="tab-cover y-mast-bg-hide" style="padding-left:0em;padding-right:0em;">Video</span></a></li> <li class="small tab "><a class="y-mast-link local" href="http://local.yahoo.com/results" data-b="http://www.yahoo.com"><span class="tab-cover y-mast-bg-hide" style="padding-left:0em;padding-right:0em;">Local</span></a></li> <li class="small tab "><a class="y-mast-link shopping" href="http://shopping.yahoo.com/search" data-b="http://www.yahoo.com"><span class="tab-cover y-mast-bg-hide" style="padding-left:0em;padding-right:0em;">Shopping</span></a></li> <li class="small lasttab more-tab "><a class="y-mast-link more" href="http://tools.search.yahoo.com/about/forsearchers.html" ><span class="tab-cover y-mast-bg-hide">More</span><span class="y-fp-pg-controls arrow"></span></a></li> HTML; $pattern = '%<a\s[^href]*href\s*=\s*[\'|"]?([^\'|"|#]+)[\'|"]?\s*[^>]*>(.*)?</a>%im'; preg_match_all($pattern, $html, $matches); The only matches I got is: Match 1 of 1: <a class="y-mast-link local" href="http://local.yahoo.com/results" data-b="http://www.yahoo.com"><span class="tab-cover y-mast-bg-hide" style="padding-left:0em;padding-right:0em;">Local</span></a> Group 1: http://local.yahoo.com/results Group 2: <span class="tab-cover y-mast-bg-hide" style="padding-left:0em;padding-right:0em;">Local</span> The pattern I made was to work in cases where the page is non-compliant to any of standard W3.
