1、获取某个class的div内的标签

获取<div class="imgList2">****</div>内的标签

方法一：

string list_page_group_str = GetValue(strResult.Trim(), "<div class=\"page both\">", "</div>");
Regex reg = new Regex(@"(?is)<a(?:(?!href=).)*href=(['""]?)(?<url>[^""\s>]*)\1[^>]*>(?<text>(?:(?!</?a\b).)*)</a>");
MatchCollection mc = reg.Matches(list_page_group_str);
foreach (Match m in mc)
{
string url = m.Groups["url"].Value + "\n";
string text = m.Groups["text"].Value + "\n";
}
