Using the FUMBBL API

#First, we define what we want to do with the API. This path here grabs the list of all matches for a team.
# This is returned in lists of 26 results per page. To make this work for all teams, there's a little bit of complexity looping through pages
# It loops making page requests and appending items to the array until it finds a page which has no games
# If you want to use your own team, set the @team_id to the id you want to play with.

#Nokogiri is ruby's XML parsing library. "open" retrieves a url and outputs the document as a string
doc = Nokogiri::XML(open(base_path + "&p=#{page}"))

draws = []

#Nokogiri uses XPath as a language to step through the nodes. This is very simple to use and learn.
