.......
请各位高手帮忙一下,谢谢谢谢

  1.   

    咦 你还在C#版发了一次
     string str = File.ReadAllText(@"E:\1.txt", Encoding.GetEncoding("gb2312"));
                Regex reg = new Regex(@"(?is)\{ylcms[^\}]+?\}.*?\{/ylcms\}");
                foreach (Match m in reg.Matches(str))
                {
                    Console.WriteLine(m.Value);
                    Console.WriteLine(); Console.WriteLine(); Console.WriteLine(); Console.WriteLine();
                }
      

  2.   


                MatchCollection matches = Regex.Matches("your html", @"(\{ylcms[^\}]*?\}[^\{]*?\{/ylcms\})", RegexOptions.IgnoreCase);
                foreach (Match match in matches)
                {
                    Console.WriteLine(match.Groups[1].Value);
                }
      

  3.   

    借用下一楼的代码 稍加改进
    string str = File.ReadAllText(@"E:\1.txt", Encoding.GetEncoding("gb2312"));
                Regex reg = new Regex(@"(?is)\{[^\}]+?\}.*?}");
                foreach (Match m in reg.Matches(str))
                {
                    Console.WriteLine(m.Value);
                    Console.WriteLine(); Console.WriteLine(); Console.WriteLine(); Console.WriteLine();
                }

    老师您好:
    刚才在那边你用这种方法
    Regex reg = new Regex(@"(?is)\{ylcms[^\}]+?\}((?!\{/?ylcms).)*{/ylcms\}");
    帮我得出了页面上所有 {ylcms:.....}.....{/ylcms}的标签内容.可是把我的 {ylcms:pagetitle/}
    这个标签过滤掉了,我想要一起显示出来,
    比如页面上有:
    <table border="0" cellpadding="0" cellspacing="0">
                <tr><td>{ylcms:title /ylcms}</td>
    <td align="left" valign="top" class="list">
                        <div class="list_title">国内大事<a href=''> 更多</a></div>
                        {ylcms:news type="11" number="20"}
                            <div>
                                国内大事<a href="(ylcms:Url/)">(ylcms:Title/)</a><span>(ylcms:Date/)</span>
                            </div>
                          <br />
                        {/ylcms}
                    </td>
                    <td align="left" valign="top" class="list">
                        <div class="list_title">国外大事<a href=''> 更多</a></div>
                        {ylcms:message type="11" number="20"}
                            <div>
                                国外大事<a href="(ylcms:Url/)">(ylcms:Title/)</a><span>(ylcms:Date/)</span>
                            </div>
                          <br />
                        {/ylcms}
                    </td>
    </tr>
            </table>  
    我想要输出的结果是包含:
    {ylcms:pagetitle/}
    {ylcms:message type="11"...}
    .......
    {/ylcms}
    {ylcms:news type="11"...}
    .......
    {/ylcms}
    请问可以再帮一下忙吗?
      

  5.   

    试试
                string str = File.ReadAllText(@"E:\1.txt", Encoding.GetEncoding("gb2312"));
                Regex reg = new Regex(@"(?is)\{ylcms[^\}]+?\}(?:(?:(?!\{/?ylcms).)*{/ylcms\})?");
                foreach (Match m in reg.Matches(str))
                {
                    Console.WriteLine(m.Value);
                    Console.WriteLine(); Console.WriteLine(); Console.WriteLine(); Console.WriteLine();
                }
