Ok So I am using the calorieking api and it crack as my xml parser (it
comes with httparty which is my consumer gem). Now I need to be able to
list the food names. How can i get data from a hash that contains
arrays? Here is what the hash looks like when pp''ed.

Just an example of how you''d output it in a view, I''m sure you
can
adapt it from there to extract whatever values you want:
<%
@parsed_response[0][''searchresults''][''category''].each
do |cat| %>
<h1><%=h cat[''name'']%></h1>
<p>
<h3>Foods</h3>
<% cat[''foods''][''food''].each do
|food| %>
<p><%=h food[''id'']%> - <%=h
food[''display'']%></p>
<% end %>
</p>
<% end %>

That code was the for the view, hence the HTML tags. You''d obviously just use the iterating code without the output in the controller.

Try working through the issue with irb and seeing what your results are and work through how you''d navigate the results.
