Nokogiri HttParty Xpath Ruby on Rails
- by Brian
I am working with a mmorpg (Eve Online) request that returns xml. I am using httparty for the request and I am trying to use nokogiri to obtain attribute values for a specific element.
Here's an example of the response:
<eveapi version="2"><currentTime>2012-10-19 22:41:56</currentTime><result><rowset name="transactions" key="refID" columns="date,refID,refTypeID,ownerName1,ownerID1,ownerName2,ownerID2,argName1,argID1,amount,balance,reason,taxReceiverID,taxAmount"><row date="2012-10-18 23:41:50" refID="232323" refTypeID="9" ownerName1="University of Caille" ownerID1="32232" ownerName2="name" ownerID2="34343" argName1="" argID1="0" amount="5000.00" balance="5000.00" reason="Starter fund" taxReceiverID="" taxAmount=""/></rowset></result><cachedUntil>2012-10-19 23:03:40</cachedUntil></eveapi>
I only need to access attributes for the element "row" and there can be many rows returned.
I have read about xpath and from what I understand if I do the following it should return all rows: doc.xpath('row') however it does not return anything.
Here's what I have so far:
options = {:keyID => 111111, :vCode => 'fddfdfdfdf'}
response = HTTParty.post('https://api.eveonline.com/char/WalletJournal.xml.aspx', :body => options)
doc = Nokogiri::XML(response.body)
doc.xpath('row').each do |r|
end
The loop is never executed.
What am I doing wrong? I need to return all row elements and gain access to each of the row's attributes.
Thanks.
