Hi Roy, As a basis for the web services alternative, you might want to look at Mark Pilgrim's Universal Feed Parser: http://feedparser.org/ Tom Tom Burton-West Senior Applications Systems Analyst Library Information Systems Getty Research Institute (310)440-7410 [log in to unmask] >>> [log in to unmask] 03/16/06 11:37 AM >>> Thank you all for your feedback, both public and private. The response was universal: it would be better to handle this with code rather than XSLT, and the best method would be a web services model where you pass in a URL for a feed and get back standard output, letting the code handle invalid XML and all the variant forms of RSS. This is exactly the solution I would like to use, and will continue to advocate with the powers that be. In this particular instance, I must be a team player and not just go and do it myself. Meanwhile, in the short-term I decided to hand-select the appropriate stylesheet for the specific feed rather than try to write a stylesheet that could handle anything. That will work for now, but before long I'll need to have an easier and less fragile method such as the ones you suggested.
