<br>&nbsp;&nbsp;&nbsp;&nbsp;如何将这句“http://newauthor2.cmfu.com/books/95133/2533771.txt”话提出来

解决方案 »

  1.   


    Regex reg = new Regex(@"\w+(><script)(?url)(</script>)");
    Match match  = reg.Match(yourstring);
    string url = match.Groups["url"].Value;
      

  2.   

    try..            string str = ".....<script src=http://newauthor2.cmfu.com/books/95133/2533771.txt></script>......";
                Match m = Regex.Match(str, @"<script\s+src=(?<url>[\S\s]+)></script>", RegexOptions.IgnoreCase);
                if (m.Success)
                {
                    Console.WriteLine(m.Groups ["url"].Value );
                }输出:
    http://newauthor2.cmfu.com/books/95133/2533771.txt
      

  3.   

    string yourStr = ..............;
    string resultStr = Regex.Match(yourStr,@"<script\s+src='([\S\s]+?)'></script>",RegexOptions.IgnoreCase).Groups[1].Value;   //要提取的内容这样虽然能把楼主要的内容提取出来，但并不是通用的表达式，很可能只适用于这一个实例，楼主如果只是想取这一个，或者形式与这个完全相同的网页内容当然无所谓，但是如果是多个网页，而<script src='http://newauthor2.cmfu.com/books/95133/2533771.txt'></script>此处出现的情况不尽相同，最好能说明一下限定条件
      

  4.   

    我用的是第一个
    TempContent 表示包含有html的字符串
    TempContent = System.Text.RegularExpressions.Regex.Replace(TempContent,"<[^>]+>","");至少一个
    TempContent = System.Text.RegularExpressions.Regex.Replace(TempContent,"<[^>]*>","");任意个
