Getting started
ScrapySharp has a Web Client able to simulate a real Web browser (handle referrer, cookies …)
Html parsing has to be as natural as possible. So I like to use CSS Selectors and Linq.
This framework wraps HtmlAgilityPack.
Basic examples of CssSelect usages
using System.Linq;
using HtmlAgilityPack;
using ScrapySharp.Extensions;
class Example
{
public void Main()
{
var divs = html.CssSelect("div"); //all div elements
var nodes = html.CssSelect("div.content"); //all div elements with css class ‘content’
var nodes = html.CssSelect("div.widget.monthlist"); //all div elements with the both css class
var nodes = html.CssSelect("#postPaging"); //all HTML elements with the id postPaging
var nodes = html.CssSelect("div#postPaging.testClass"); // all HTML elements with the id postPaging and css class testClass
var nodes = html.CssSelect("div.content > p.para"); //p elements who are direct children of div elements with css class ‘content’
var nodes = html.CssSelect("input[type=text].login"); // textbox with css class login
}
}
Scrapysharp can also simulate a web browser
ScrapingBrowser browser = new ScrapingBrowser();
//set UseDefaultCookiesParser as false if a website returns invalid cookies format
//browser.UseDefaultCookiesParser = false;
WebPage homePage = browser.NavigateToPage(new Uri("http://www.bing.com/"));
PageWebForm form = homePage.FindFormById("sb_form");
form["q"] = "scrapysharp";
form.Method = HttpVerb.Get;
WebPage resultsPage = form.Submit();
HtmlNode[] resultsLinks = resultsPage.Html.CssSelect("div.sb_tlst h3 a").ToArray();
WebPage blogPage = resultsPage.FindLinks(By.Text("romcyber blog, Just another WordPress site")).Single().Click();
