关于正则提取网址的问题，在线等~十万火急

[怎么来这一出]

获取一个html源码，然后提取里面的符合条件的网址，比如http://style.sina.com.cn/industry/2012-10-08/1147106801.shtml这种，结尾是若干数字+“.shtml”结尾的网址，怎么用正则表达式做到呢？

匹配出来，在判断下
修改这样

            string s = "http://style.t.sina.com.cn/index.shtml http://roll.style.sina.com.cn/fas/jewelry/index.shtml http://roll.style.sina.com.cn/time/guide/index.shtml http://roll.style.sina.com.cn/tas/cigar/index.shtml http://roll.style.sina.com.cn/tas/club/index.shtml http://roll.style.sina.com.cn/lei/hotels/index.shtml http://roll.style.sina.com.cn/lei/cars/index.shtml http://roll.style.sina.com.cn/lei/yachting/index.shtml http://roll.style.sina.com.cn/des/architecture/index.shtml http://roll.style.sina.com.cn/industry/index.shtml http://style.sina.com.cn/industry/2012-10-08/1147106801.shtml";
            
            Regex re = new Regex(@"[a-zA-z]+://[^\s]*");

            MatchCollection mc = re.Matches(s);

            string t = string.Empty; 

            foreach (Match  m in mc)
            {
                if (Regex.IsMatch(m.ToString(), @"[a-zA-z]+://[\s\S]*?/[0-9]+.shtml"))
                {
                    System.Diagnostics.Debug.Print(m.ToString());
                }
            }
            //输出 http://style.sina.com.cn/industry/2012-10-08/1147106801.shtml

([/w-]+/.)+[/w-]+.([^a-z])(/[/w- ./?%&=]*)?|[a-zA-Z0-9/-/.][/w-]+.([^a-z])(/[/w- ./?%&=]*)?
或
