How to understand the DLL component AngleSharp of xHTML source code, in view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and easy way.

AngleSharp is a DLL component developed specifically for parsing xHTML source code based on .NET (C #).

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

I will mainly introduce some common methods of using AngleSharp. I will use the site as a prototype to introduce to you. Other similar components are:

Domestic: Jumony

Github address: https://github.com/Ivony/Jumony

Abroad: Html Agility Pack

Project address: http://htmlagilitypack.codeplex.com/

Specifically, you can search and compare the differences and performance of the three. Next, we mainly discuss that the protagonist is AngleSharp.

Introduce AngleSharp into the project and use the NuGet tool to execute commands (I'm actually pretending. ) Install-Package AngleSharp

Add a reference Using AngleSharp to the project

First, let's get the HTML source code for the home page of CnBlogs

Static public string GetHtml () {HttpWebRequest myReq = (HttpWebRequest) WebRequest.Create ("https://www.jb51.net"); 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 ();}

Get the title of all current blog posts on the jb51 home page

Private static void Main (string [] args) {/ / find all article titles string cnblogsHtml = GetHtml (); / / load HTML var document = DocumentBuilder.Html (cnblogsHtml); / / must be used here = = cannot be used 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 output of the above code:
