# 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

```C#

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

```C#

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();

```
