Module: XblGamercard::MicroScraper

Included in:

Gamercard, GamercardGame, LiveProfile

Defined in:

lib/xbl_gamercard/micro_scraper.rb

Overview

Really simple scraper DSL for objects that have a root node and want to extract data from the root node’s children.

The class must have a method called ‘element` that returns the root node.

The various extract methods all take a CSS selector, and optionally a hash of options and a block. The block is applied to the first node (for extract methods), or mapped to each node (for extract_all methods).

Options are:

• :as - The name of the method that is generated.

• :from - The name of the method that returns the root element.

  class XblGamercard

  include XblGamercard::Microscraper
  
  # The following are all equivalent
  extract("#Gamertag", :as => "gamertag") { |e| e.text }
  extract_text "#Gamertag"
  
  extract_int "#Gamerscore"
  extract_text("#Gamerscore", &:to_i)
  extract("#Gamerscore") { |e| e.text.to_i }
