假设您将使用HTML解析器HtmlAgilityPack（您的问题中有标记）：

WebClient client = new WebClient();
string downloadString = client.DownloadString("http://www.mywebsite/mypage");

HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(downloadString);
//string whatUrLookingFor = doc.GetElementbyId("syllabus-stages").InnerHtml;
string whatUrLookingFor = doc.GetElementbyId("syllabus-stages").Attributes["data-url"].Value;
