Question

I’m using Nokogiri to parse XML data that I’m getting from the roar engine after I create a user. The XML looks like below:

<roar tick="135098427907">
  <facebook>
    <create_oauth status="ok">
      <auth_token>14802206136746256007</auth_token>
      <player_id>8957881063899628798</player_id>
    </create_oauth>
   </facebook>
</roar>

I’m totally new to Nokogiri. How do I get the value of status, the auth_token and player_id?

Answer 1

str = "<roar ......"
doc = Nokogiri.XML(str)
puts doc.xpath('//create_oauth/@status')  # => ok
puts doc.xpath('//auth_token').text       # => 148....
# player_id is the same as auth_token

And it is a great idea to learn you some good xpath from w3schools.
