正责表达式

求助正责表达式

CSS code

([\s\S]*?)/isU' ,$str , $match);
preg_match_all('/href="([\s\S]*?)"/' , $match[1][0], $href );
print_r($href);exit();

function getHtml($url){
        if(function_exists('file_get_contents')){
            $file_contents = file_get_contents($url);
        }
        else{
            $ch = curl_init();
            $timeout = 5;
            curl_setopt ($ch, CURLOPT_URL, $url);
            curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
            curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
            $file_contents = curl_exec($ch);
            curl_close($ch);
        }
        return $file_contents;
    }

我要得到分集连接，
但是结果是 连接多了点，要去掉。主要是匹配范围的时候多了点内容，不知道怎么样去掉。还请知点一下。、


我要得到的效果是：
