[bushido]

string target = @"<(table)\s+[.\n]*>[.\n]*<(table)\s+[.\n]*>[.\n]*<img\s+src\s*=""(?<img>)""\s+[.\n]*>[.\n]*<\/.*><\/table.*>";
我这样写能不能匹配

[leisang]

网上教程很多了，自己搜一下
search.csdn.net

[bushido]

哎,我是急用才,
教程我也在看

[bushido]

string target = @"^<(table)\s+.*>.*<(table)\s+.*>.*<img\s+src\s*=""(?<img>)""\s+.*>.*</table></table>$";
我改成這樣還是不行呀

[bushido]

Regex re = new Regex(@"这里怎么写");
foreach (Match m in re.Matches(str)){
Console.WriteLine(m.Groups["xxxx"].Value);
Console.WriteLine(m.Groups["yyyy"].Value);
}
//这里的，xxxx,yyyy怎么对应
