Parsing HTML Tool ANGLESHARP Introduction

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

Project Address: Https://github.com/FlorianRappl/AngleSharp

I mainly introduce is some use anglesharp commonly used method, with everybody introduction, I will take http://www.cnblogs.com site as the prototype. Other similar components are:
Domestic:jumony
GitHub Address: Https://github.com/Ivony/Jumony
Author Blog address: http://www.cnblogs.com/Ivony/
Abroad:Html Agility Pack
Project Address: http://htmlagilitypack.codeplex.com/
In particular, we can search for the difference and performance of the three by ourselves. Next, we'll discuss the main character Anglesharp .

• Introduce Anglesharp to the project and execute the command with the NuGet tool (actually I'm faking it.) ）Install-Package AngleSharp

• Adding references using Anglesharp in your project

• First we get the HTML source code of Cnblogs home page

  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();}

• Get the title of all current blog posts on cnblogs home page

  private static void Main (string[] args) {//Find all article title string cnblogshtml = Gethtml ();

      //加载HTML    var document = DocumentBuilder.Html(cnblogsHtml);    //这里必须要使用== 不能使用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 has provided the detailed document and the example, everybody may go to look. The biggest advantage of this plugin is that it supports output Javascript,Linq syntax,ID and Class selectors, dynamically adding nodes, and supporting Xpath syntax. The real. NET development of the tool.
