HttpwebReponse取部分内容问题

Question

用HttpwebReponse取一个网页的部分内容

如 ：这个网页地址 http://seo.chinaz.com/?host=www.fjkaineng.com&c=1&m=1

要这个网页的红色框里的内容，如下图：



要怎么做才可以获得红色框里的内容？

我只懂得取得整个网页的内容，懂不得要怎么处理文件流获得部分内容？能给个列子吗(结合JS或Jq等都可以的)？

 protected string httpRequsetToString()

        {
            string str = null;
            try
            {
                HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create("http://seo.chinaz.com/?host=www.fjkaineng.com&c=1&m=1");
                req.Method = "GET";

                //获取本次的回馈,先创建接收回馈的类HTTPWEBRESPONSE
                HttpWebResponse myHttpWebResponse = (HttpWebResponse)req.GetResponse();
                //创建接收回馈的字节流类
                Stream receiveStream = myHttpWebResponse.GetResponseStream();//得到回写的字节流 
                Encoding encode = System.Text.Encoding.UTF8;
                StreamReader readStream = new StreamReader(receiveStream, encode);

                str = readStream.ReadToEnd();
                readStream.Close();
            }
            catch (Exception Ex)
            {
                throw new Exception(Ex.Message);
            }

            return str;
        }

你好,

    我建议你去尝试HTML Agility Pack.

HTML Agility Pack：簡單好用的快速 HTML Parser

http://msdn.microsoft.com/zh-tw/ee787055.aspx

例子：

            //HtmlDocument htmlDocument = new HtmlDocument();

            //htmlDocument.LoadHtml(str);

            HtmlWeb webClient = new HtmlWeb();

     HtmlDocument doc = webClient.Load("http://www.w3.org/");

 

    HtmlNodeCollection nodes = doc.DocumentNode.SelectNodes("/html[1]/body[1]/div[1]/div[2]/div[3]/div[2]/div[1]/div[1]/div[1]/div");

    foreach (HtmlNode node in nodes)

    {

        Console.WriteLine(node.InnerText.Trim());

}
