Answer 2

这些是其中的一小段,下面还很多,我想提取的是stop_name=??后面??的内容,比如平海路,十四中,希望高手可以指点,谢谢..

Answer 3

如果不考虑性能问题,也可以简单点
先用String.IndexOf() 取得第一个"stop_name="的索引,然后把后面的内容截取出来;再把前面已经截取的部分SubString掉,对剩下的内容继续执行String.IndexOf() 直到没有匹配伪代码如下:
String s = "..........html内容........";
int i = 0;
while(s.IndexOf("stop_name=")>=0)
{
......
}

Answer 4

用split，"stop_name=" 为分割关键字

Answer 5

string content = "<a   href=\"line_more.jsp?stop_name=十四中\"   target=\"_blank\"> ";
            string regex = "<a[\\s\\S]+?stop_name=(?<keyword>.*?)\"[\\s\\S]+?>";
            System.Text.RegularExpressions.RegexOptions options = ((System.Text.RegularExpressions.RegexOptions.IgnorePatternWhitespace | System.Text.RegularExpressions.RegexOptions.Multiline) 
                        | System.Text.RegularExpressions.RegexOptions.IgnoreCase);
            System.Text.RegularExpressions.Regex reg = new System.Text.RegularExpressions.Regex(regex, options);            System.Text.RegularExpressions.MatchCollection resultes = reg.Matches(content);
            foreach (System.Text.RegularExpressions.Match item in resultes)
            {
                //item.Groups["keyword"].Value就为其stop_name的值
                //Response.Write(item.Groups["keyword"].Value);
                //MessageBox.Show(item.Groups["keyword"].Value);
            }
