Specify the url to the Oracle Magazine RSS Feed. get method. 5, available. In the callback method if status is ‘ok’ get the result of the request. Create a REXML::Document object from the result using the new constructor. Using the REXML::XPath class iterate over the//rss//item elements in the RSS feed using the REXML::XPath:each method, which returns an array of nodes, and create a CatalogRSSFeed object corresponding to each node using the create method of the model. In the index action create an instance variable for all feed results using the find(:all) method.
