Easy import with NuGet

Getting started

  1. Start a new console project and add Nuget Reference
  2. PM> Install-Package Net.RafaelEstevam.Spider.Simple.Lib
  3. Create a class for your spider (or leave in program)
  4. create a new instance of SimpleSpider
    1. Give it a name, cache and log will be saved with that name
    2. Give it a domain (your spider will not fleet from it)
  5. Add a event FetchCompleted to
  6. Optionally give a first page with AddPage. If omitted, it will use the home page of the domain
  7. Call Execute()
void run()
    var spider = new SimpleSpider("QuotesToScrape", new Uri(""));
    // Set the completed event to implement your stuff
    spider.FetchCompleted += fetchCompleted_items;
    // execute
void fetchCompleted_items(object Sender, FetchCompleteEventArgs args)
    // walk around ...
    // TIP: inspect args to see stuff

    var hObj = args.GetHObject();
    string[] quotes = hObj["span > .text"];

TIP: Use the Simple.Tests project to see examples and poke around
