I'm working on creating an aggregator for a custom xml file (not rss). I'll use feedapi and feed element mapper. Please explain the advantages/disadvantages of feedapi_node versus feedapi_data.
For context of my project, I will be collecting from over 1000 sites that may each have up to 500 sets of element data within each xml file. I'll need it to delete data no longer in the xml file, add new data, or update data. From there, I'm planning to use views to display the collected information, with the user being able to filter the results. I don't need comments. Images and files will be linked to third party site and not stored on my server. Lightweight and speed are needed.
Here's my main concern -- some of the children elements have repeating sets, sometimes unlimited, (contact - name, phone, email ; contact - name, phone, email; ...). Any help in pointing me in the right direction is greatly appreciated!
