你试过HtmlAgilityPack吗？它将允许您解析和查询（使用XPATH）您找到的许多格式错误的HTML。

如果我正确理解您的问题，您可以使用：

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;

提取div的InnerHtml？
