Hi Tim,
You will want to test your regex with a Java Regex tester see http://www.freeformatter.com/java-regex-tester.html however Im not sure if that option will achieve what you wish.
Did you want to use the RSS feed as a URL crawl list? If so you can abstract this script to create a list of start urls to index. (Just run as a pre_gather_command)
