I have created a module to parse XML data and turn them into EE variables that you can place in your template . The results can be cached into database for better performance. It is based on XML_Walk from Solspace(www.solspace.com). Special thanks to Mitchell. It is originally written to handle XML data and with a few tweaks, it can also be used to extract data from RSS/Atom feeds.
Full documentation can be viewed once you install the module.
See the following examples to get some ideas if this fits your needs. Feel free to modify or customize it to suit your needs. I only implemented it in a way to deal with what I need. You may need to add some other parameters like “limit” or “backspace” or conditions…etc
