A new tutorial on the ProDevTips.com website today shows how to parse tags (like in a feed) with the Zend_Feed component of the Zend Framework.
Consuming a feed with Zend Feed is quite simple if you don’t want to do something fancy.
They include an example of how to pull in the feed, parse out information from the various tags, and push that information into a database they've created (they include the code for the script and to create the database as well).
