如何获取ID后面的数字？
字符串为s=“<a class="click_tag play_3g_link" src2="http://dl.ctmus.cn/res/1068/mp3/00/12/71/1068001271000800.mp3" id="2238" act="imusic">”
如何用这则表达式的方式查找并获取.mp3" id="后面id的值2238？ --------------------编程问答-------------------- (?is)<a\s*class="click_tag play_3g_link"\s*src2="[^"]*?/([^/]*?\.mp3)"\s*id="([^"]*?)"[^>]*?> --------------------编程问答-------------------- 用juqsery 很好获取 --------------------编程问答--------------------
string s = @"<a class=""click_tag play_3g_link"" src2=""http://dl.ctmus.cn/res/1068/mp3/00/12/71/1068001271000800.mp3"" id=""2238"" act=""imusic"">";
string r = Regex.Match(s, @"(?is)<a class=""click_tag play_3g_link""[^>]+?id=""(?<id>.+?)""[^>]+>").Groups["id"].Value;
Response.Write(r);
补充：.NET技术 , C#
