本文关键字：我的 编程 运行 HtmlAgilityPack 网站 | 更新日期: 2023-09-27 18:10:26

我在mp3.zing网站上写了一个编程获取值。但HtmlAgilityPack错误。我的代码如下: 

string trave = "";          
String url = "http://mp3.zing.vn/bang-xep-hang/bai-hat-Viet-Nam/IWZ9Z08I.html";
HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
HtmlWeb a = new HtmlWeb();
doc = a.Load(url);
HtmlNodeCollection t =doc.DocumentNode.SelectNodes("//a[@class='"txtprimary'"]");
foreach (var i in t){ trave += i.InnerText; }

错误的形象http://postimg.org/image/5uuqby5ov/

您的代码中存在一些问题。

1-下载压缩后的内容

2-选择正确的锚。

String url = "http://mp3.zing.vn/bang-xep-hang/bai-hat-Viet-Nam/IWZ9Z08I.html";
var data = new WebClient().DownloadData(url);
var html =  new StreamReader(new GZipStream(new MemoryStream(data), CompressionMode.Decompress)).ReadToEnd();
HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
doc.LoadHtml(html);
var t = doc.DocumentNode.SelectNodes("//a[@class='txt-primary']")
        .Select(a => a.InnerText)
        .ToList();
输出:
