I have a table view that lists job postings for an app pulling from an RSS feed. Unfortunately, quite a few of the job postings that have expired are still left in the feed. The only piece of information that my app could utilize to know that the job is no longer posted (because it uses a link to go to the job posting page) is the fact that when you click on the link and the UIView is pushed, the link that shows up is expired with a message stating, we apologize for the inconvenience, but this position's status has recently changed. On older posts it doesn't load (these are typically posts that start with docs.sitename.doc) and then there's the File not found message without a noted URL redirect link. Is there any direct method worth looking into to possibly filtering these out? At least to where I could note that the positions have expired?
