您是否试过HtmlAgilityPack？它将允许您解析和查询（使用XPATH）很多您找到的格式错误的HTML。

如果我正确理解你的问题，你可以使用：

HtmlAgilityPack.HtmlWeb web = new HtmlAgilityPack.HtmlWeb(); 
HtmlAgilityPack.HtmlDocument doc = web.Load("http://abc.com/xyz.html"); 

HtmlAgilityPack.HtmlNode div = doc.DocumentNode 
    .SelectSingleNode("/html/body/div[@class=\"os-box unround\"]"); 
string contentYouWantedToDisplayOnYourOwnPage = div.InnerHtml;
