正则替换标记之间的文字

[guohouchang]

//<a target="_blank" href="/xxxx.aspx">AAAA</a> 替换成<a target="_blank" href="/xxxx.aspx">BBB</a>
Regex reg = new Regex(@"<a \s(0,n)>.+?</a>" , RegexOptions.IgnoreCase | RegexOptions.Multiline);
            string strFiltered = reg.Replace(<a target=\"_blank\" href=\"/xxxx.aspx\">AAAA</a>", "BBB");

正则不对。谁帮改下~

string html = @"<a target=""_blank"" href=""/xxxx.aspx"">AAAA</a>";
		Regex reg = new Regex(@"(<a.+?>).+?</a>");
		string strFiltered = reg.Replace(html, "$1BBB</a>");
		Response.Write(strFiltered);

  string s = "<a target=\"_blank\" href=\"/xxxx.aspx\">AAAA</a>";
        string snewtext = "BBB";

         s = Regex.Replace(s, "(<a.*?>)(.*?)</a>", "$1" + snewtext + "</a>",RegexOptions.Singleline|RegexOptions.IgnoreCase);
