[兔子-顾问]

string result = Regex.Match(yourHtml,@"(?<=onclick=')[^']+").Value;

能这样吗比如要在id="eimg_1" li标签里 onclick的内容

[兔子-顾问]

string result = Regex.Match(yourHtml,@"(?is)(?<=id="eimg_1"[^<>]+?onclick=')[^']+").Value;

[兔子-顾问]

string result = Regex.Match(yourHtml,@"(?is)(?<=id=""eimg_1""[^<>]+?onclick=')[^']+").Value;
