The solution is here (it’s actually a solution that’s been around for a few years, now), and was developed, modified and jimmied around by Tim Baxter and Jamon Abercrombie as a way to parse MULTIPLE feeds through a single, simple script.
This is really simple to use, modify and customize. Find a valid feed URL that you want to use, place it where it says to, follow the instructions that are provided in the comments, modify how you want each item parsed out, upload it and you’re pretty much done.
Let us know if you have questions or comments. There are ways to customize this and modify it to do just about whatever you need. It is in use on at least 15 sites (that we know of), and has been customized to various levels on each one. This is definitely not a cookie-cutter script that can only be used one way. There are countless ways to implement this thing. If you want to use it, but aren’t sure … ask. We’ll be happy to help.
