Introduction to AngleSharp, an HTML Tool

AngleSharpIs A. NET (C #)-Based DLL component specially designed for parsing xHTML source code.

Project address: https://github.com/FlorianRappl/AngleSharp

I mainly introduce some usageAngleSharpI will take the http://www.cnblogs.com site as the prototype. Other similar components include:
China:Jumony
Github address: https://github.com/Ivony/Jumony
Author Blog address: http://www.cnblogs.com/Ivony/
Foreign countries:Html Agility Pack
Address: http://htmlagilitypack.codeplex.com/
For details, you can search for the differences and performance of the three items. Next we will discuss the main roleAngleSharp

• Introduce AngleSharp to the project and use NuGet to execute commands (in fact, I am installing force .)Install-Package AngleSharp

• Add reference Using AngleSharp to the Project

• First, obtain the HTML source code of the CnBlogs homepage.

  static public string GetHtml(){    HttpWebRequest myReq =    (HttpWebRequest)WebRequest.Create("http://www.cnblogs.com");    HttpWebResponse response = (HttpWebResponse)myReq.GetResponse();    // Get the stream associated with the response.    Stream receiveStream = response.GetResponseStream();    // Pipes the stream to a higher level stream reader with the required encoding format.     StreamReader readStream = new StreamReader(receiveStream, Encoding.UTF8);    return readStream.ReadToEnd();}

• Obtain the title of all current blog posts on the Cnblogs Homepage

  Private static void Main (string [] args) {// find the title of all articles string cnblogsHtml = GetHtml ();

  // Load HTML var document = DocumentBuilder. html (cnblogsHtml); // you must use = here. You cannot use Equals var titleItemList = document. all. where (m => m. className = "titlelnk"); int iIndex = 1; foreach (var element in titleItemList) {Console. writeLine (iIndex + ":" + element. innerHtml); iIndex ++ ;}}

The official website provides detailed documents and examples. You can take a look. The biggest advantage of this plug-in: Support for outputJavascript,LinqSyntax,IDAndClassSelector and dynamically add nodes. It is a powerful tool for. NET development.
