    }

        //Method 2: use htmlToHtmlDoc
        string testUrlWithXmlns = "http://sd.csdn.net/";
        string respHtml = getUrlRespHtml(testUrlWithXmlns);

        //<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
        //<html xmlns="http://www.w3.org/1999/xhtml">
        //<head>
        HtmlAgilityPack.HtmlDocument htmlDoc = htmlToHtmlDoc(respHtml);

注意，使用此函数之前，需要开启对应的宏USE_HTML_PARSER_HTMLAGILITYPACK，以及添加对应的dll库HtmlAgilityPack.dll的引用。
